Air temperature and humidity calibration

In our laboratory, calibration is carried out by comparing the customer’s instrument with our reference standard. We can calibrate 0°C to 50°C for air temperature and 5% to 95% for relative humidity.

Air speed calibration

Based on IEC 61400-12-1:2017 (Annex F: Wind tunnel calibration procedure for anemometer). In our air speed calibration laboratory carried out in Eiffel type wind tunnel that allow the calibration of the most common anemometers such as: cup anemometer, pitot tube anemometer, thermal anemometer, 2D ultrasonic anemometer in the range from 0.5 m/s to 30 m/s.

Wind direction calibration

The calibration of wind direction sensors is very important to ensure the correct evaluation of gathered measurement data. In our laboratory we carried out based on IEC 61400-12-1:2017 (Annex N: Wind tunnel calibration procedure for wind direction sensors) to calibrate the most common wind direction sensor such as: Wind vane direction, ultrasonic wind direction from 0 to 360 degree.

Atmospheric pressure & Pressure gauge calibration

Gas flow measuring device calibration

In our laboratory using a compact piston prover "DryCal 800" as a reference standard, to provides an accurate flow measurements. The DryCal 800 is more than 4x more accurate than most flow meters and are recognized for their accuracy by flow professionals worldwide. We can calibrate gas flow measuring device from 5 to 50000 sccm.
