Air Quality Dust Monitors

Hand-Held Direct Reading Fume and Dust Detector.

DustMate

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 PM1concentrations.
  • Internal sampling pump
  • Reference filter for gravimetric calibration
  • Ergonomic case allows single-handed operation at arms length
  • Internal 32k memory records results
Turnkey’s new iPM instrument employs a unique combination of light extinction and light scatter

IPM Plus

Turnkey’s new iPM instrument employs a unique combination of light extinction and light scatter to accurately analyse individual airborne particles. This allows the instrument to simultaneously measure all the PM size fractions with great accuracy.

Unlike fan-based samplers, iPM has a proper pump, air filter, and accurate flow controller to generate a stable sample airflow. It also generates recirculated clean air to keep its optics away from dust and dirt contamination. Its proprietary long-life pump uses an ultrasonic mechanism and is virtually noiseless. The filter capsule is interchangeable and can be sent for material analysis of the collected dust.

To remove water droplets when sampling in damp or misty conditions, the iPM has a temperature-controlled heated inlet. The user can adjust the sample temperature set point. Or, if an ambient T & RH probe is fitted, the sample flow can be held at constant humidity.

iGASair

iGASair is our internet gas monitor, which can measure 6 different gas species simultaneously.

iGASair connects to Turnkey’s AirQWeb cloud server, and can be used alongside our range of dust and vibration & noise instruments to allow integrated monitoring of a wide range of environmental measurements.

Gas sensors are housed in a shielded manifold and aspirated with an ultra-quiet pump, making it suitable for outdoor and indoor air pollution monitoring.
  • Records up to 6 gas species simultaneously
  • Automatic zeroing virtually eliminates drift
  • Integrated with AirQWeb for live monitoring
  • Can be used alongside Turnkey dust monitors
  • Usable with our solar/wind off-grid power system
