Overview
GDW-500B low/high temperature test chamber is produced by ZKHS, which is suitable for the performance detection of aviation, aerospace products, information electronics, Instruments, materials, electricians, electronic products and various electronic components in high and low temperature environment. The box body is processed by numerical control machine tool, which is beautiful and easy to operate.
Features
1. The box body is processed and formed by numerical control machine tool, which is beautiful and generous in shape, and adopts no-reaction handle, which is easy to operate.
2. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate, and the outer shell of the box is sprayed with A3 steel plate to increase the appearance texture and cleanliness.
3. The large observation window is equipped with lights to keep the box bright, and the tempered Glass embedded in the heating element can be clearly observed in the box.
4. The left side of the box is equipped with a 50mm diameter test hole, which can be used for external test power or signal wires.
5. The temperature control adopts a "7.0" inch large-screen Touchscreen temperature and humidity control instrument, which has simple operation settings and a locking function.
6. With P.I.D automatic calculation function, it can immediately correct the temperature change conditions, making the temperature control more accurate and stable.
7. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit, and the refrigeration system adopts the unit or binary low temperature circuit system design.
8. The multi-wing blower is used for strong air circulation to avoid dead ends and ensure uniform temperature distribution in the test area.
9. The air path circulates the air outlet and return air design, the wind pressure and wind speed meet the test standards, and the temperature stabilizes quickly at the moment of opening the door.
10. Heating, cooling, and complete system independence can effectively reduce testing costs, increase lifespan, and reduce failure rates.
Principle
The test chamber sets the temperature conditions through the large-screen Touchscreen temperature and humidity control instrument, and uses the automatic calculation function of P.I.D. to precisely control the temperature. The refrigeration system adopts the original French "Taikang" fully enclosed Compressor unit and unit or binary low temperature circuit design, combined with the multi-wing blower strong circulation air supply to ensure uniform temperature distribution in the test area. The heating system adopts a fully independent nickel-chromium alloy electric heating heater to achieve rapid heating and stable control.

2. Enter the test conditions and parameters through the large-screen Touchscreen temperature and humidity control instrument.
3. The controller lock function is enabled to avoid human touch to change the temperature value.
4. Start the device, and the system automatically performs P.I.D calculations and temperature control.
5. Use observation windows and lighting to monitor the situation inside the box.
6. The test time is set to be adjustable from 0 to 9999 minutes or hours.
7. After the test, turn off the device and disconnect the power supply.
Notice
• Operating Environment Temperature should be in the range of 5 ℃~ 30 ℃, humidity ≤ 85% R.H.
• Power frequency meets AC280V +/- 10% or AC380V +/- 10% 50Hz three-phase five-wire requirements.
• Avoid opening doors frequently while the equipment is running to maintain a stable temperature.
• Regularly check the safety protection device, including leakage, short circuit, overtemperature, motor overheating, Compressor overvoltage, overload, overcurrent protection.
• Use the 50mm diameter test hole on the left side of the box when connecting the external test line, and pay attention to the safety of the cable.
• During equipment maintenance, ensure power-off operation to prevent the risk of electric shock.
