performance. While the best RH sensor may boast an intrinsic accuracy of ±1%, calibration errors can render them useless. All secondary RH sensors require calibration to a higher standard, not only during production, but also as part of ongoing maintenance to correct for drift. Good calibration cannot save a bad sensor, of course, but
The need arose for a temperature and relative humidity calibration system that is capable of simultaneously calibrating a number of highaccuracy temperature and relative humidity sensors. These sensors have temperature accuracy specifications as low as ±°C over the temperature range 16 to 24°C, and ±°C over the range 15 to 35°C.
Long term exposure to conditions outside normal range, especially at high humidity, may temporarily offset the RH signal ( +3%RH after 60h at >80%RH). After returning into the normal temperature and humidity range the sensor will slowly come back to calibration state by itself. Prolonged exposure to extreme conditions may accelerate ageing.
