Overview
HZAOC GDJS-800E High and Low Temperature Alternating Damping heat testing chamber is suitable for inspecting 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 to ensure sealing.
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 French "Taikang" fully enclosed Compressor, use R404A environmentally friendly refrigerant, and the refrigeration system is safe and reliable.
6. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life.
7. Adopt steam boiler electric heating and humidification method, with water level control and anti-dry burning device.
8. The control system adopts High Accuracy Digital Temperature and Humidity Controller, which does not drift for long-term operation.
9. The control system is equipped with multiple safety protections such as phase loss, over-temperature, and leakage, as well as independent over-temperature protectors.
10. 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 Compressor refrigeration, and the heating and humidification systems are realized by electric heaters and steam boilers respectively. The control system adjusts the solid-state relay through PID according to the feedback of the Sensor, and precisely controls the output of heating, cooling and humidification, so as to realize the set temperature and humidity alternating cycle. The box adopts the upper air supply and lower return air mode to ensure uniform temperature and humidity.
