Chamber Summary
centrifugal air circulation chamber LCD Display Temperature Humidity testing chamber is used to detect materials in the environmental performance of equipment and test various materials resistance to heat, cold, dry, performance.performance.For mobile PC case, electronic, electronics, communication, instrument, vehicles, plastic, metal, food, chemical, building materials, medical, aerospace and other products of quality.
Working principle
Circulating Air Chamber Automatically Adjust Cold - Hot Temperature Humidity Chamber (heating and cooling) and humidification is composed of two parts. Through installation in box within top Department of rotating fan, will air row into box achieved gas cycle, and balance box within of temperature, and humidity, by box built-in of temperature, and humidity sensor collection of data, biography to temperature, and humidity controller (micro information processing device) for edit processing, issued thermostat adjustable wet instruction, through air heating unit, and condensation tube and sink within heating evaporation unit of common completed.
Control system
Imported microcomputer temperature controller integrated controllers (humidity display percentage).
Accuracy range accuracy: ± 0.1%R ± 0.1 ° c, humidity temperature · H, indicating accuracy: ± 0.1 ° c, temperature is ± 0.1%R · • Platinum platinum resistance temperature and humidity sensors · PT100Ω.
Completely independent system of heating system, NI-CR alloy electric heating heater.
Humidification system external insulation type, stainless steel boiler type surface evaporative type humidifier.
Circulatory system and temperature of low-noise air conditioner motors, vane centrifugal wind wheel.
Main features
1. high quality appearance, body recovery arc shape, surface treated with matte stripes, and the plane no reaction, easy operation, safety and reliability.
2. view of complex layers of rectangular glass window, you can observe using guinea pigs in a test, Windows with sweat-proof electric appliance to prevent condensation water droplets, and PL high brightness fluorescent lamp keep the lighting inside the box.
3. door double insulation airtight stringency, effectively isolating the internal temperature leaking.
4. the external water supply system, convenient to add humidification bucket of water, and automatically recycled.
5. compressor circulation system by France, "Taikang" brand, can effectively remove the condenser and capillary tube of lubricant and a full range of environmental protection refrigerant (R23, R404, R507).
6. the controller adopts imported LCD display screen and can display both the measured value and the setting value and time.
7. the controller has more than one program and temperature and humidity can be done quickly (OUICK) or slope (SLOP).
8. built-in moving pulley for easier movement and place and has a strong positioning screw location.
