E+E Elektronik - CALIBRATION

Calibration intervals for E+E Elektronik humidity and temperature sensor products is once per year.  SensorPros recommends the calibration equipment listed in the table below for following E+E product collections:  Humidity-for Process ControlHumidity-Modules & Probes AND Humidity-HVAC Transmitters

    The calibration of your E+E Elektronik Relative Humidity Sensors depends on the application, and accuracy of the sensor model you have.

    Calibration Method #2:
    Single Point Salt Solutions - Calibration Method

    The E+E Elektronik humidity standards shown below are salt solution based. By placing them inside the "HA101401 Calibration Device", and then subsequently inserting your relative humidity probe you can perform calibrations. Because they are single range calibration standards, for multipoint calibrations you would need to change out the salt solution for that standard value and put in the next one. Or you can purchase several HA101401's and fill each one with a particular RH standard value. This method of calibration is time-consuming and requires each calibration to stabilize which can take up to 1/2 hour or more for each calibration point. If you have the time, using the salt solutions is a cost-effective method from the capital investment point of view, but becomes less attractive when considering the labor cost. It just takes a long time to perform multi-point relative humidity calibrations.

    What calibration standard points (values) you choose to use are up to what your measuring range is.

    The salt solution for that percent RH value is placed inside the device, then the probe is inserted that is to be calibrated.
