Overview
HZAOC GDJS-800C 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 SUS304B stainless steel plate, the outer side is Cold rolled steel plate sprayed, and the thermal insulation material is 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 built-in special heating wire to prevent frost, and a lighting lamp.
4. The side of the box is equipped with a φ 50mm test hole, and the stopper is a silicone rubber low foam material with high and low temperature resistance.
5. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor unit, using R404A environmentally friendly refrigerant.
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, equipped with PT100 Sensor, accurate and stable control.
9. It is equipped with multiple safety protection measures, including phase loss, over-temperature, leakage, etc., and an independent over-temperature protector.
10. The air supply method is the upper air supply and the lower air return, and the temperature sensor is placed in a trend.
Principle
The test chamber adjusts the temperature and humidity in the working room 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 High Accuracy temperature and humidity controller performs PID adjustment according to the feedback of the Sensor to realize the set temperature and humidity alternating cycle.
Applications
Electrical and electronic products, components, parts and materials moisture resistance test, high and low temperature environmental adaptability test, storage test, transportation test, use environment simulation test

The data did not mention specific compliance criteria
Steps
Connect 380V +/- 10% power supply.
2. Set the required Temperature range (-40~ 150 ℃), Humidity range (30~ 98% RH), lifting temperature rate and timing time (0~ 999h) through the buttons on the operation panel.
3. Place the sample in the studio.
4. Start the equipment, and after the circulating fan runs, the heating and humidification system starts to work according to the set program.
5. During the test, the conditions in the box can be observed through the observation window lighting.
6. After the test reaches the set time, it is automatically stopped or manually stopped, and the sample is removed.
Notice
• Power supply voltage meets 380V +/- 10% requirement before equipment operation.
The equipment is equipped with an interlock device, and the heating and humidification system cannot be started when the circulating fan is not started or overloaded.
• When using the test hole, pay attention to the sealing and insulation of the stopper.
• During the operation of the equipment, in case of failure such as overtemperature, the protection system will act, and it needs to be troubleshooted before rerunning.
• Regularly check whether the water level control device and heater anti-dry burning device are normal.
• Please pay attention to the high voltage part of the system during maintenance, and refer to the high voltage meter to monitor the operating status.
