Overview
HZAOC GDJS-010B 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 also be used 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 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, built-in anti-frost 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 air supply method of upper air supply and lower air return, 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. Adopt steam boiler electric heating and humidification method, with water level control and anti-dry burning device.
9. The control system adopts High Accuracy Digital Temperature and Humidity Controller, equipped with multiple safety protection measures.
Principle
The test chamber adjusts the temperature and humidity of the air in the working room through the evaporator, electric heater, humidifier and fan in the air conditioning cabinet. The refrigeration system adopts a cascade refrigeration cycle, and realizes low temperature control through a Compressor and an evaporative condenser. The heating and humidification systems control the electric heater and the electric heating humidification tube through solid state relays respectively, and the temperature and humidity controller performs PID adjustment according to the feedback of the Sensor to realize the set temperature and humidity environment and its alternating process.
Applications
Electrical and electronic products, components, parts and materials moisture resistance test, high and low temperature environment storage adaptability test, transportation adaptability test, use adaptability test
Standards
The data did not mention specific compliance criteria
Steps
The information does not provide specific operation steps
Notice
* Power supply voltage 380V +/- 10%.
Before running, ensure that the circulating fan starts normally, otherwise the heating and humidification system will not work.
Pay attention to the water level control device to prevent the humidifier from dry burning.
* The equipment is equipped with test holes, and it is necessary to ensure that the stopper sealing is good when using it to maintain the environment in the box.
The equipment is equipped with multiple safety protections (such as phase loss, over-temperature, leakage, etc.), and the fault indicator light should be checked in time.
* There is an independent over-temperature protector outside the main controller, but the Reliability of the control system still needs to be checked regularly.
* The refrigeration system is equipped with a high voltage protection device, and the high voltage meter should be monitored during operation.
When operating at low temperatures, the heating wire of the observation window can prevent frost formation and ensure normal lighting for observation.
