Model RH-4019 Programmable Constant Temperature and Humidity Test Chamber
(Environmental Testing Chamber)
Applicable Scope
The programmable constant temperature and humidity test chamber is applied to test the capabilities of heat-resistance, cold-resistance, dry-resistance and moisture-resistance of materials. It is mainly used in testing the adaptability of electronics, electrical appliances, food, automobile, rubber and plastic, metal and other products, parts and materials in the high and low temperature and humid environment when storage, transport and using.
Description
1. Touch screen.
2. Inner material: SUS#304.
3. Tecumseh Compressor.
4. High quality and lowest price.
Technical Characteristics
1. High-texture appearance, the body adopted an arc shape, surface matte stripes processing, and flat-handle, easy to operate, safe and reliable.
2. Rectangular multi-layer glass View window, the use of guinea pigs observed in the test window with anti-sweat heaters device prevents water gas condensate ,Knot, water droplets, PL fluorescent lamps to keep the inside lighting.
3. Door bunk isolated airtight packing, can be effectively isolated from the internal temperature of the leak.
4. With external water supply system, convenient to supplement the cylinder water supply, and automatic recovery using.
5. Compressor cycling system used France“Tecumseh”brand which can effectively remove condenser pipe and between capillary Lubricating oil and whole series adopt environmental protection refrigerant (R23, R404, R507)
6. Controller uses the imported LED display screen, can display measured values and setting time
7. Controller with multi-segment program editor and temperature and humidity can be fast (OUICK) or slope (SLOP) controlled.
8. Built-in mobile wheels allow easy movement and placed and have a strong positioning screw position.
