Calibration of humidity instrumentation is essential to maintain accurate and reliable measurements. Unlike other measurement sensors for parameters such as temperature and pressure, humidity sensors must be in direct contact with the environment to be measured. As such, humidity sensors are therefore more likely to have their performance impaired by chemical contamination, surface corrosion, particulate deposits and mechanical damage. Correct sensor protection and routine calibration checks are the only way to quantify the effect these factors have on measurement performance.
ROTRONIC offer a range of calibration options to satisfy most needs.
