Rh-4019 programmable constant temperature and humidity test chamber
Applicable Scope
Constant temperature and humidity test chamber can program is suitable for the aerospace, electronic electrician, ship railway, automobile motorcycle, quality measurement and scientific research units, institutions of higher learning, enterprises and institutions, all kinds of electronic elements and other products of spare parts and materials in high temperature, low temperature, constant temperature and stored under hot and humid environment and the adaptability when using test, test their various performance indicators, is the product test simulation environment necessary testing equipment.
Technical Characteristics
1. High quality appearance, the body adopts arc shape, the surface is treated by the stripe of the mist surface, and the plane has no reaction handle, easy to operate, safe and reliable.
2. Rectangular laminated glass viewing window, which can be used for observation of test products in the test. The window is equipped with anti-perspirant electric heater device to prevent water vapor condensation droplets, and high-brightness PL fluorescent lamp to keep the lighting inside the box.
3. The door is sealed with double layers to prevent air tightness and effectively prevent internal temperature leakage.
4. With an external water supply system, it is convenient to replenish the water supply from the humidifying bucket, and can be recycled automatically.
5. The compressor circulation system adopts the French "taikang" brand, which can effectively remove the lubricating oil between the condensing pipe and the capillary pipe, and the whole series adopts the environmental protection refrigerant (R23, R404, R507).
6. The controller adopts imported LCD display screen, which can display the measured value, set value and time at the same time.
7. The controller has multiple program editing and temperature and humidity can be quickly (OUICK) or slope (SLOP) control.
8. The built-in movable pulley is easy to move and put and has a strong positioning screw fixed position.
