Relative Humidity Test Kit

The relative humidity test kit is great for testing the accuracy of our detachable RH/T-S1 and RH/T-S3 relative humidity sensors. The air inside the test kit bottle is controlled by a salt solution, which keeps the relative humidity constant. The kit is available with either 33% or 75% relative humidity (Order asRH/TK/33 and RH/TK/75 respectively).

RH/TK/33 (Price: $125.00)

RH/TK/75 (Price: $125.00)

RH/T-S1

Detachable relative humidity/temperature sensor that is included with Navigator Pro and HT-4000. Can be used to obtain ambient RH/T readings. Order individually or in packs of 5 as RH/T-S1/5.

Order as:

RH/T/S1 (Price: $80.00)
