Dustlight Mini Personal Dust Monitor
Wearable personal dust monitor for site managers, EHS advisers, and operatives working in construction, renovation, and industrial environments where respirable dust concentrations pose a direct risk to respiratory health. It measures respirable dust alongside PM1, PM2.5, and PM10 fractions in real time using a photometric laser-based sensor and a colour-coded traffic light alert system that signals immediately when concentrations rise towards configurable threshold levels. It connects to a free companion app for data logging, exposure trend analysis, and limit value configuration to match UK EH40 Workplace Exposure Limits.
How real-time detection closes the gap that traditional dust sampling misses
Gravimetric dust sampling collects airborne particles on a filter over a shift and sends them to a laboratory for analysis, returning results days after the exposure has already occurred and the operative has continued working throughout. A site manager relying solely on periodic sampling has no way of knowing in the moment whether dust controls are working, whether RPE is being worn when it is actually needed, or whether a specific task is generating concentrations that require immediate action. The Dustlight Mini addresses that gap by measuring dust concentrations continuously at the breathing zone and alerting the wearer immediately when levels cross a threshold that warrants a response, giving the operative and the site manager information they can act on during the shift rather than after it.
Key Features
-
Photometric laser-based sensor: Uses a Class I laser at 660nm to measure airborne particle concentrations continuously. Detects respirable dust, PM1, PM2.5, and PM10 simultaneously from a single unit, with the first stable reading within 30 seconds of start-up.
-
180° traffic light LED alert system: Illuminated panels on the front, top, and right-hand side of the housing change from green to amber to red as concentrations rise through configurable thresholds. Requires no language skills or interpretation, making it effective across any site workforce regardless of language or experience.
-
Configurable limit values: Default thresholds are preset for general dust on delivery. Via the free Dustlight app, values must be reconfigured to match the relevant EH40 Workplace Exposure Limits for the specific dust type in use on a UK site before the device is deployed.
-
Material-specific calibrations: Seven dust configurations are available alongside the general dust standard: silica, hardwood dust, softwood dust, welding fumes, oil mist, aluminium oxide, and diesel particulate matter. Each adjusts sensor sensitivity to account for the optical and density properties of that material.
-
Klick Fast modular attachment: The rear of the device accepts Klick Fast connectors from a range of over 20 carrying accessories, including belt clips, chest straps, Velcro wristbands, and clothing patches. The standard plastic clip is included; Klick Fast accessories are available separately.
-
Up to 40-hour battery life: Three operating modes selectable via the app. Continuous mode keeps display and wireless permanently active (up to 7 hours). Standard mode, the factory default, times out the display and wireless after inactivity whilst continuing to measure (up to 20 hours). Eco mode reduces brightness and connectivity further (up to 40 hours).
-
Repair-friendly design: All modules and housing parts are individually replaceable, extending operational service life and reducing long-term cost of ownership.

Who is this for
The Dustlight Mini is designed for EHS professionals, site managers, and operatives working in environments where respirable dust is generated as a routine part of daily operations. It is particularly suited to construction and refurbishment sites during cutting, grinding, drilling, and mixing operations, as well as woodworking workshops, welding and fabrication areas, and industrial facilities where fine particulate concentrations can rise rapidly during task-intensive periods. Procurement and safety compliance teams managing multi-site operations will find the Corporate software plan's fleet management and centralised exposure reporting well matched to large-scale deployment requirements across multiple locations and teams.
Typical applications
-
Continuous personal monitoring during concrete cutting, drilling, and grinding on construction and civil engineering sites where silica dust is generated in concentrated bursts.
-
Monitoring dust exposure during internal fit-out and renovation tasks where plasterboard, concrete, and masonry dust is generated in enclosed spaces with limited natural ventilation.
-
Real-time alerting during hardwood and softwood sanding, routing, and sawing in carpentry and joinery workshops, using the material-specific wood dust configuration to reflect the lower exposure thresholds for wood dusts.
-
Assessing the effectiveness of on-tool extraction and local exhaust ventilation systems by measuring residual dust concentrations at the breathing zone while extraction is active.
-
Monitoring welding fume concentrations during fabrication and site welding operations with the dedicated welding fumes calibration active, supporting compliance with HSE guidance on welding fume control.
-
Identifying dust source hotspots in production facilities, warehouses, and industrial environments where particulate generation varies by process or working location.
-
Supporting COSHH risk assessments by providing indicative, time-stamped concentration data for specific tasks and materials to inform control measure selection and RPE specification.
-
Prompting operatives to don appropriate RPE when concentrations reach the amber threshold, and to escalate dust controls or cease work when the red limit is exceeded.
How to use
Step 1: Charge the device fully before first use using the included USB magnetic cable connected to a certified 5V, 1A USB power source. The LCD display shows charging progress. Use only the supplied cable and a CE-marked or equivalent certified charger.
Step 2: Download the free Dustlight app from the Apple App Store or Google Play Store (search "Dustlight"), or access the web app at app.dustlight.com. Create a free account using your name and email address.
Step 3: Connect the app to the device via Bluetooth. On first connection, select United Kingdom as the country of operation. Reconfigure the limit values to match the relevant EH40 Workplace Exposure Limit for your specific dust type before deploying on a UK site. The device arrives preset with German TRGS 900 thresholds, which do not correspond to UK WELs.
Step 4: Select the material configuration relevant to your working environment from the available options in the app: general dust, silica, wood dust, welding fumes, or another available configuration.
Step 5: Press and hold the side button for at least 2 seconds to switch the device on. Wait 30 seconds for the first stable measurement reading to appear on the display.
Step 6: Attach the device close to the breathing zone using the included clip or a Klick Fast accessory. Breast pocket or chest strap position is recommended. The air inlet on the front of the device must face outward and must never be obstructed by clothing, PPE straps, or equipment at any time.
Step 7: Monitor normally throughout the shift. Green indicates concentrations are below the warning threshold. A single beep and amber display signal that the warning threshold has been reached and preventive action should be considered. Three rapid beeps and a red display signal that the configured limit value has been exceeded and immediate action is required.
Step 8: After each shift, sync the device to the app to store and review the measurement record. Export data as a CSV file for COSHH documentation or inclusion in site health and safety records.
Common mistakes
-
Covering the air inlet: the air inlet on the front of the device must never be obstructed by clothing, PPE straps, or equipment at any point during use. A covered inlet produces inaccurate readings and can fail to detect hazardous concentrations entirely.
-
Failing to configure UK limit values: the device arrives preset with German TRGS 900 thresholds, which do not correspond to UK EH40 Workplace Exposure Limits. UK operators must configure the correct values via the app before using the alert system to inform any site safety decision.
-
Treating it as a compliance tool: the Dustlight Mini provides indicative measurements only. It must not be used as the sole basis for COSHH compliance decisions or as a substitute for formal gravimetric sampling by an accredited occupational hygienist.
-
Using outdoors in rain or wet conditions: the device is not waterproof. Use is restricted to indoor environments and protected outdoor spaces. Moisture ingress risks permanent damage to the sensor unit and housing and is not covered by the manufacturer warranty.
-
Neglecting maintenance notifications: the device monitors its own sensor service life and alerts the user when the 80% threshold is reached. Ignoring these notifications allows measurement accuracy to degrade progressively. Book professional servicing via www.dustlight.de before the maintenance deadline passes.
Safety
The Dustlight Mini contains a Class I laser radiation source operating at 660nm with output below 0.39mW, classified as safe in accordance with IEC 60825-1:2014. The housing must not be opened or modified under any circumstances, as doing so exposes the internal laser and creates a serious injury risk. The device is not certified for use in potentially explosive or flammable atmospheres and must not be operated where combustible gases, vapours, or dust clouds may be present. It is not a medical device and must be kept at a safe distance from sensitive medical equipment in clinical environments. Charge only using the supplied cable with a certified 5V USB power source marked CE or equivalent. Battery replacement must be carried out by an authorised Dustlight Service Partner only. Annual maintenance by Latai GmbH or an authorised partner is required to maintain sensor accuracy and warranty validity.
Maintenance
Wipe the external housing after each shift with a dry microfibre cloth or soft brush to remove surface dust accumulation. For stubborn residue, use a slightly damp cloth without cleaning agents, solvents, or aggressive chemicals, taking care that no moisture enters the air openings. The stainless-steel air inlet grille can be removed for cleaning under running water with a brush and mild detergent; allow it to dry completely before reinserting. Never use compressed air or a vacuum cleaner on the air duct or sensor openings, as this can permanently destroy the internal measurement components. The app displays the current sensor service status and alerts the user when 80% of the maintenance threshold has been reached.
Frequently Asked Questions
Q: What is the difference between the three battery modes?
A: Continuous mode keeps the LED display and wireless connection permanently active, providing up to 7 hours of battery life, suited to short intensive monitoring sessions. Standard mode, the factory default, switches the display and Bluetooth off after 5 minutes of inactivity whilst continuing to measure, extending runtime to up to 20 hours. Eco mode reduces display brightness and limits wireless activity further, giving up to 40 hours per charge, making it viable for multi-shift deployment without recharging between uses. Mode selection is made via the Dustlight app.
Q: What is the Dustlight Mini NOT suitable for?
A: The device is not suitable for use in rain, standing water, or wet outdoor conditions as it is not waterproof. It must not be used in potentially explosive or flammable atmospheres. It cannot substitute for formal gravimetric sampling for COSHH compliance purposes, and must not be used as the sole basis for any occupational health and safety decision. It is not a medical device and must be kept away from sensitive medical equipment in clinical settings.
Q: How does the Klick Fast attachment system work and what accessories are available?
A: The Dustlight Mini ships with a plastic clip for direct clothing attachment. This clip can be replaced with a Klick Fast connector (sold separately, code PP190001) that fits into the cloverleaf recess on the rear of the device and locks with a quarter-turn screw. Once fitted, it accepts over 20 accessories from the Klick Fast range, including 4-point chest harnesses (PPRE0001) and adjustable Velcro armbands (PPRE0002). Accessories slide in until they click and release by turning the device 180 degrees. Positioning the device at collar or chest height places the air inlet as close to the breathing zone as possible, which is the correct position for personal monitoring.
Q: How often does the device need professional maintenance?
A: The device uses an intelligent maintenance algorithm that calculates the required service interval based on actual usage time and dust concentrations encountered, with an absolute maximum of 12 months regardless of use. A notification appears on the display and in the app when the sensor service life reaches 80% of its threshold, and the warning remains active each time the device is started until maintenance is completed.
Q: Can multiple devices be managed centrally across a large site or multiple sites?
A: The included Basic plan stores data locally on the user's smartphone and suits individual use. The Business plan adds cloud storage, STEL and TWA exposure monitoring, multi-device access, and incident event logging, suited to larger sites running several units simultaneously. The Corporate plan is designed for organisations deploying device fleets across multiple sites, with centralised team management, hierarchical access controls, and cross-site exposure analytics.
