Replacing the humidity sensor of the HMP110 and HMP113 is not necessary in normal operation. If the accuracy of the probe does not seem to be within specification, it is likely that the accuracy can be restored by performing the adjustment procedure.

Follow this procedure to replace the humidity sensor of the HMP110 and HMP113 in case it has been damaged, or normal adjustment is not sufficient to restore the measurement accuracy. Calibration and adjustment of the humidity measurement is required after the sensor change.

To perform this procedure, you need a new HUMICAP® 180R/180V sensor. It is also recommended that you replace the filter with a new one.

  1. Remove the filter from the probe by turning it counter-clockwise.
  2. There are 2 sensors under the filter, the HUMICAP® sensor and a temperature sensor. Identify the HUMICAP® sensor. Do not touch the temperature sensor.
  3. Pull out the old HUMICAP® sensor and insert a new one. Handle the new sensor by the plastic frame.
    CAUTION Do not touch the sensor plate.
  4. Perform a 2-point adjustment of the RH measurement.
  5. Attach a new filter on the probe.
