How to calibrate the reusable Hygro-i2 Relative Humidity Probe?

May 18th 2021

Probes can be calibrated regularly with the calibration salt check. To carry out the calibration open the salt chamber and let it acclimate with surrounding ambient conditions for at least 30 minutes.
Keep the probes in the same environment.
Insert the probe in the salt chamber and leave for 40 minutes
Check the probe with CMEX5, CMEX2, MRH3 to make sure the reading is 75% Relative Humidity.
A probe calibration check is recommended within 30 days of testing.
If the probe got saturated, leave it to dry out and check with the calibration salts.
