6) Customer asks in DTM-320 manual, measurement range is 0%~100% but operating
environment is only 0 to 90% non-condensing –> so whether these two information
The sensor measurement range can work for 0~ 100% RH
but the operating environment 0 ~ 90% RH(Non Condensing) is for the meter itself.
There is no conflicts with each other.
Besides, 100% RH is close to water and this will cause meter damaged for
all electronics devices. Therefore, it is recommended to keep the sensor and meter dry
to extend its reliability and usage life.
