SELECTING A HUMIDITY SENSOR
As there no real physical standard for relative humidity calibration, humidity instruments are not specified properly. And it makes it really difficult for a user to compare the sensors from different manufacturers. This makes it mandatory for a user to go deeper into the specifications and attempt to verify the claims of the instrument manufacturer. Various sensor characteristics, viz., accuracy, linearity, hysteresis, calibration errors, long term stability of sensor and electronics, needs to be examined using the support documentation from the OEM.
