1. Introduction
Sanwood constant temperature and humidity test chamber is widely
used in scientific research, research institutes, quality
inspection institutes and other industries to do warm and humid
heat tests of electronic and electrical products, materials, parts,
equipment, etc., alternating heat test and constant temperature
test, high and low temperature routine tests, low temperature
storage,etc, in order to evaluate the performance of the sample
under given environmental conditions.
For mask condition, the temperature humidity test chamber can be
used to simulate the test conditions per EN136:
1) Dry atmosphere of 70±3 ℃
2) Atmosphere of 70±3 ℃ and 95%RH ~ 98%RH
3) Low temperature -30±3 ℃
