Product Description
The Rapid Temperature Change High and Low Temperature Humidity Test Chamber is used to test the heat resistance, cold resistance, dryness resistance, and humidity resistance of various materials. Suitable for use in electronics, electrical appliances, automotive, metal, chemical, and building materials factories.
The Balanced Temperature and Humidity
Control System (BTHC) uses P.I.D. to control the SSR, ensuring that the
system's heating and humidification capacity equals the heat and humidity loss,
thus enabling long-term stable use.

Product Features
1. The temperature rise and fall process
curve is stable and maintains a constant slope change.
2. The evaporator adopts a unique pure
copper fin design to dissipate heat more quickly and evenly.
3. Appearance spray coating or stainless
steel is optional. The stainless steel surface is treated with matte stripe
drawing, and the color of electrostatic spray coating can be freely selected.
4. Multi layers glass observation window,
which can be used for observing the test object during the experiment. The
window is equipped with an anti-sweat electric heater device to prevent water
vapor condensation and droplets, and a high brightness LED light to maintain
illumination inside the box
5. The double-layer isolation and airtight
tightness of the box door can effectively isolate internal temperature leakage.
6. The touch screen controller can
simultaneously display measured values, set values, time, etc.
7. The optimized design scheme ensures that
the machine operates with a noise level of ≤ 65dB.
Imported refrigeration components such as "Tecumseh fully enclosed
compressor from France", "Emerson compressor from the United
States", "Bitzer semi enclosed compressor from Germany", and
"GEA semi enclosed compressor from Germany" are used to form an
energy-saving, efficient, and environmentally friendly refrigeration system.
