① The three box control modes of dry and wet bulb temperature control, temperature rise control and humidity saturation control are adopted, which can meet the requirements of iec60068-2-66, jesdec-a110 and a118 specifications;

② Excellent temperature and humidity precision control logic to prevent the mode selection of moisture and condensation of the tested product;

③ The pressure value is detected by actual induction to ensure the accuracy of temperature, humidity and pressure value;

④ Three channel high-temperature protection device, moisture water cut-off protection and electric water cut-off and air combustion protection, automatic removal of saturated steam pressure when the machine stops, pneumatic mechanism pressure protection, etc;

⑤ Multiple bias voltage terminals can be selected to meet the experimental specification requirements of jesd22-a110;

⑥ Humidity can be freely selected, and saturation (100%r.h humidity) and unsaturated (75%r.h humidity) can be freely set.
