Depending on the application, the filter should be checked regularly for soiling, and replaced if necessary.
HC2A probes have high long term stability and do not require any additional calibration as supplied.
Long term stability is better than 1 %rh per year. We recommend calibrating the probe every 6 to 12 months, depending on the application. Applications where the probe is exposed to contaminants may require more frequent verifications. Calibration or Adjustment can be carried out using the HygroSoft or with the HP31/32/GTS hand-held calibrator.
Check on ProcessSensing.com for the latest version of the firmware. In order to update the firmware, the HygroSoft and the AC3001 cable are required. The HC2A probes can only be updated via HygroSoft.
