Humidity Calibration

ETI's In-House Humidity Laboratory

Importance of Regular Calibration

Confidence in the accuracy of humidity measuring instruments such as hygrometers is essential. As with most digital equipment, there is a tendency for drift over a period of use, making regular calibration an important part of hygrometer upkeep. 

The Best Equipment

ETI's in-house UKAS-accredited humidity laboratory is equipped with two of the world's premier humidity chambers. The Thunder Scientific 2500 is armed with two-pressure technology to generate controlled humidity conditions. The new HYGROGEN2 - HG2-XL chamber, meanwhile, generates stable temperature and humidity conditions in rapid time.

Increased Efficiency

Accurate monitoring of humidity can help businesses become more productive. Employers are also realising the importance of healthy working environments, which includes the control of humidity to help prevent airborne bacteria, eliminate static shocks and reduce eyestrain.

Air Temperature Capability

ETI's humidity laboratory is also UKAS accredited for air temperature measurement certification. We can test the temperature in air across a range spanning from 0°C to 65°C, 

with a Calibration & Measurement Capability (CMC) of 0.15°C.
