Programmable Constant Temperature And Humidity Testing Machine



Machine is made of stainless steel:


Powder paint outside the box


Equipment summary:


The machine is applied to test the materials in heat-resistance, cold-resistance, dry-resistance, moisture-resistance. It is simple to operate and program easy to edit. It can show the set values and operative time.




1.High-texture appearance, the surface handled through the matte stripes, and use of planar non-reactive handles, easy to operate, safe and reliable.

2.Rectangular complex glass window can be viewed the testing sample, windows with anti-sweat heater device that prevents water vapor condensation, and high-brightness PL light.

3.Double-insulated airtight container, which can effectively isolate the internal temperature of leakage.

4.With an external water supply system can be easy to supply water and automatically reuse.

5.Compressor circulatory system from French "Taikang", more effective removal of oil between the condenser and the capillary and use environmentally refrigerants (R23, R404, R507).

6.Controller imported LCD display screen can be displayed measuring values and setting the value and time.

7.Controller with multi-segment program edited, temperature and humidity can be controlled quickly (OUICK) or slope (SLOP).

8.Built-in mobile pulley easy to move and has a strong positioning screw fixed position
