DustMate - Hand-Held Direct Reading Fume and Dust Detector

DustMate is a hand-held instrument with a very fast response which has been designed to locate sources of workplace airborne dust and fumes even at very low concentrations. Highly effective for checking air quality within buildings. Its one second time resolution also allows it to be used as a road-side indicator to identify high pollution vehicles as they pass.

The instrument will continuously indicate the concentration of thoracic, inhalable and respirable particles down to 0.1 micrograms per cubic metre. In its environmental mode, it will indicate TSP, PM10, PM2.5 and PM1 concentrations.

Airborne Particle Monitors

Turnkey Instruments design and manufacture a range of easy to use instruments which continuously measure and record the concentration of airborne particles. In their environmental mode these instruments can simultaneously monitor the concentrations of TSP, PM10, PM2.5 and PM1 particles. Alternatively, in their workplace mode, the inhalable, thoracic and respirable fractions can be monitored.

An internal reference filter can be used to confirm the gravimetric calibration of the instruments.

All instruments feature internal data logging for the particle concentrations. Osiris and Topas also allow wind speed and direction, temperature, humidity, rainfall and two external gas or noise meter inputs to be recorded at the same time.

All instruments use our own proprietary nephelometer. A pump continuously draws an air sample through the nephelometer which analyses the individual particles as they pass through a laser beam. These same particles are then collected on the reference filter. The nepholometer’s dedicated microprocessor can analyse individual particles even if there are millions of them per litre. This allows size fractions to be determined at concentrations up to several mg/m3. Above this there is an indicator range which can be used without sizing up to 60 mg/m3.

AirQ for Windows

Environmental Monitoring Software

AirQ the user friendly and quick reporting PC software, designed in house will manage and display results from our range of environment sensors. These sensors can be used to measure air quality information including: PM10 and PM2.5 particles, airborne fibres and noise. Climatic conditions such as ambient temperature, wind speed and direction, relative humidity, etc. can also be recorded as an aid to tracking the source of the pollution. For example, with AirQ a live “on-screen” pollution rose can readily be created which plots measurements against wind heading on a polar chart.

AirQ can be used to control sensors and record measurements in real-time with “live” graphs and tables appearing on the PC screen (It can automatically start and stop sensors at chosen times of day, either on daily or weekly cycles). It can also upload results stored in a sensor’s memory. AirQ keeps the results in folders which can be searched by it’s powerful database engine. These folders can be printed, exported for archive purposes, or pasted via the Window’s Clipboard to other applications.

Networked Environmental Monitoring

Creating a network of sensors has never been easier. Any number of sensors can be connected to an AirQ network created with any combination of fixed wiring (up to 10km), licence free radio telemetry (up to 20km), telephone and GSM cellular modems. A unique feature of the network is that as each new sensor is connected it automatically informs the PC of what it is designed to measure, what its engineering units are, what remote control features are available and so on. In this way future expansion of the system is assured. A network can also include alarm facilities such as beacons or sirens for early warning and response to high readings.
