Overview
HZAOC GDJS-800A High and Low Temperature Alternating Damping heat testing chamber is suitable for investigating the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, as well as the adaptability test of storage, transportation and use in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is stainless steel plate, and the outer side is sprayed Cold rolled steel plate, with good thermal insulation performance.
2. The door is made of double-decked silicone rubber sealing material, which has strong sealing properties.
3. The observation window is a multi-layer conductive film tempered hollow Glass, built-in anti-frost heating wire and lighting.
4. Equipped with test holes with silicone rubber plugs for both thermal insulation performance.
5. Adopt the air supply method of upper air supply and lower air return, and the temperature sensor is placed in a trend.
6. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor and uses R404A environmentally friendly refrigerant.
7. The refrigeration system is equipped with multiple safety protections such as high voltage control, overvoltage and overload.
8. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life.
9. Adopt steam boiler electric heating and humidification method, with water level control and anti-dry burning device.
10. High Accuracy Digital Temperature and Humidity Controller for accurate and stable control.
11. The control system is equipped with multiple safety protections such as phase loss, over-temperature, and leakage, as well as independent over-temperature protectors.
12. The electrical control system is equipped with interlocking devices to enhance safety.
Principle
The test chamber adjusts the temperature and humidity of the air in the box through evaporators, electric heaters, humidifiers, fans and other equipment in the air conditioning cabinet. The refrigeration system adopts a cascade refrigeration cycle to achieve rapid cooling through Compressors, condensers, evaporators and other components. The heating and humidification systems generate heat and humidity through electric heaters and steam boilers respectively. Sensor signals are received by the High Accuracy temperature and humidity controller, and PID control is carried out through solid-state relays to achieve accurate and smooth exchange of temperature and humidity.
