The sensor laboratory has the latest, modern equipment for testing and calibrating all types of gas and particle sensors.

Sensor calibration and validation of particle measuring instruments

Our laboratory for calibration of gas and particle sensors has instrumentation for generating gases at known concentrations, from the ppb range to the % range. In addition, the laboratory contains a large number of reference instruments for checking interferences, temperature, moisture, etc.

The specialists at the sensor laboratory are developing new techniques for gas generation with an aim of performing cost-effective calibrations of microsensors.

At the sensor laboratory, we can also validate instruments for measuring airborne particles, including sensors for the determination of particle numbers and Black Carbon (soot particles).

In the sensor calibration laboratory, we can conduct:

  • Testing and validation of gas sensors
  • Cost-effective calibration of microsensors
  • Testing and validation of particle sensors.
The sensor laboratory has equipment for dosing known concentrations of gases and particles, including ultrafine particles and Black Carbon (soot particles).
