Overview
HZAOC GDJS-100B 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 stainless steel plate, the outer side is sprayed steel plate, and the thermal insulation performance is good.
2. The door is sealed with double-decked silicone rubber, and the observation window is equipped with frost-proof heating wire and lighting.
3. The refrigeration system adopts the French "Taikang" fully enclosed Compressor and environmentally friendly refrigerant, and the operation is safe and reliable.
4. The heating system uses a porcelain frame nickel-chrome wire electric heater, which has little thermal inertia and long service life.
5. The humidification system adopts steam boiler electric heating method and is equipped with anti-dry burning device.
6. The control system adopts High Accuracy Digital Temperature and Humidity Controller, equipped with multiple safety protection functions.
7. Equipped with independent over-temperature protectors and system interlocking devices, providing high safety.
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 temperature control adopts PID signal to adjust the heater through the solid state relay, the humidification is realized by the steam generated by the electric heating tube, and the refrigeration system circulates the refrigerant through the Compressor to cool down. The box adopts the upper air supply and lower air return mode to ensure uniform temperature and humidity.
Applications
Test on moisture resistance and high and low temperature adaptability of electrical and electronic products, components, parts and materials

Steps
The information does not provide specific operation steps
Notice
• Power supply voltage (380V +/- 10%) is required.
• Make sure that the circulating fan starts normally before operation, otherwise the heating and humidification system will not work.
• Pay attention to the water level control device to prevent the heater from dry burning.
• Regularly check whether the system protection devices (such as over-temperature protectors, leakage protection, etc.) are reliable.
• When using the test hole, pay attention to the sealing and thermal insulation efficiency of the stopper.
Equipment is equipped with a variety of safety protections, but safety regulations must still be followed during operation.
