IEC 60068-2 Programmable Temperature And Humidity Chamber , Wide
Temperature Control Range
Product information:
The test device is designed and manufactured according to IEC 60068-2, Test methods-test A: cold, test B: dry heat, test Cab: damp heat, steady state, test Db: damp heat, cyclic.
Feature:
1. It has an extremely wide temperature control range to meet the various needs of users.
2. It adopts a unique balanced temperature adjustment and humidity
control mode to adjust the ideal temperature and humidity
environment. With stable, balanced heating and humidifying
capability, it can control high temperature and high stability
temperature and humidity.
3. Automatic selection of refrigeration circuit: The automatic
control device has the function of automatically selecting the
running refrigeration circuit with the set value of temperature,
and realizes the cooling of the chiller directly under the high
temperature state. The refrigeration adopts the air-cooled
compressor unit and adopts the fully enclosed compressor.
4. The door is equipped with a light observation window, which is
convenient for observing the test state of the test sample.
