Product Description

High Low Temperature Humidity Test Chamber Environmental Humidity Test Chamber


           The humidity test chamber is suitable for the whole machine, parts, materials for constant high temperature, low temperature or temperature cycle conditions test.The humidity test chamber can be used for the heat dissipation test sample and non-heat dissipation

test sample test. For the test of heat dissipation test sample, heat dissipation power can not exceed the cooling capacity of the refrigeration system of humidity test chamber, because the control of temperature is a dynamic balance process, at different temperature points, the cooling capacity of the refrigeration system is also accompanied by changes.

  • Outer chamber material: cold rolled steel plate + double-sided electrostatic spraying process
  • Inner chamber material: SUS304 high-grade stainless steel plate
  • Insulation material: rigid polyurethane foam + aluminum silicate insulation layer


The structural strength:
  • Bearing capacity of test chamber floor: ≤120kg (uniform load)
  • Test chamber sample frame bearing capacity: ≤20Kg (uniform load)
  • The total weight of the test box shall not exceed 150kg


Heating Mode:

The closed-loop feedback heating control system is composed of temperature sensor, central controller, solid-state relay drive module and heater actuator. Through THE P.I.D control calculation method, the temperature compensation control of the test chamber studio can be carried out in real time and dynamically.
