Overview
HZAOC GDJS-100A 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, and can be used as an adaptability test equipment for storage, transportation and use in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is SUS304B stainless steel plate, the outer side is Cold rolled steel plate sprayed, and the thermal insulation layer is made of ultra-fine Glass thermal insulation cotton.
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, with anti-frost built-in heating wire and lighting.
4. The side of the box is equipped with a test hole with a silicone rubber plug, which has both thermal insulation efficiency.
5. Adopt the upper air supply and lower return air mode, 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 heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertia and long service life.
8. The humidification system adopts the steam boiler electric heating humidification method, and is equipped with water level control and dry burning prevention devices.
9. The control system adopts High Accuracy Digital Temperature and Humidity Controller, which does not drift for long-term operation.
10. The control system is equipped with multiple safety protections such as phase loss, over-temperature, and leakage, as well as independent over-temperature protectors.
Principle
The test chamber adjusts the temperature and humidity of the air in the working room through equipment such as evaporators, electric heaters, humidifiers and fans in the air conditioning cabinet. The refrigeration system uses a cascade refrigeration cycle to achieve rapid cooling through components such as Compressor, condenser, evaporator, etc. The heating and humidification systems are driven by solid-state relays controlled by PID to achieve precise temperature and humidity control. The control system coordinates the operation of cooling, heating, humidification and fans according to the set program to simulate the required temperature and humidity environmental conditions.
