Ihc-200-wifi extend sensor cable

Hello I was wondering if I could manually extend the humidity sensor cable for the ihc-200-WiFi? If so what gauge wire should be used? I’m also assuming this will effect the calibration and the unit would have to be recalibrated with a saturated salt test.

Thank you!

Sorry the IHC-200-WIFI probe cable is not recommended to be extended, it may damage the unit during the extension process or affect the accuracy of the readings.
