Overview
HZAOC GDJS-50C 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 French "Taikang" fully enclosed Compressor unit, use R404A environmentally friendly refrigerant, and the refrigeration system has multiple safety protections.
6. The heater adopts a porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life; the humidification adopts the steam boiler electric heating method, and is equipped with a water level control and anti-dry burning device.
7. The control system adopts High Accuracy Digital Temperature and Humidity Controller, equipped with PT100 Sensor, stable and reliable control.
8. The control system is equipped with multiple safety protections such as phase loss, over-temperature, and leakage, as well as independent over-temperature protectors.
9. The electrical system is equipped with an interlock device to ensure that the heating and humidification system cannot be started when the fan is not started or overloaded.
Principle
The test chamber adjusts the temperature and humidity of the air in the box through the evaporator, electric heater, humidifier and fan in the air conditioning cabinet. The refrigeration system adopts a cascade refrigeration cycle to achieve rapid cooling through the Compressor, condenser, evaporator and other components. The heating and humidification system is controlled by a solid state relay. The electric heater and the electric heating humidification pipe work respectively. The closed-loop PID adjustment is carried out by the High Accuracy temperature and humidity controller and the Sensor to realize the set temperature and humidity alternating program. The box adopts the air circulation mode of upper air supply and lower air return to ensure uniform temperature and humidity.
