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).
Frequently Asked Questions about the Sensor Laboratory
There are no restrictions on the type of gas analysers, and in principle no restrictions on the types of gases we can produce at known concentrations.
Standard gases are typically NO2, NO, CO2, SO2, methane and other gases, which can be produced in certified/accredited mixtures in pressurised cylinders. But we also produce ozone (O3), water vapour (H2O), HCl, HF, etc. through special dosing equipment.
We can produce gases at known concentrations from the ppb range and up to the % range.
Calibration of ozone monitor using gas phase titration when dosing ozone and NO.
Validation of particle sensors when dosing known particle sizes and measurement by reference instrument.
The above graphs and table show how the sensors deviate upon repeated measurements at dosed, traceable concentrations. This is described in a calibration certificate that is applies to the instrument tested.
