Humidity (without condensation) Note1,2 Note 1,3

Note 1: Background color changes slightly depending on ambient temperature. This phenomenom is reversible.

Note 2: Ta ≤ 70ºC: 75 RH max; Ta > 70 ºC: absolute humidity must be lower than the humidity of 75% RH at 70ºC

Note 3: Ta at -30ºC will be <48 hrs, at 80ºC will be <120 hrs when humidity is higher than 75%.
