Overview
GDW-800D low/high temperature test chamber is produced by ZKHS, which is suitable for aerospace products, information electronic Instruments, materials, electricians, electronic products and various electronic components in high and low temperature or heat and humidity environment inspection of its performance indicators. The box body is processed by numerical control machine tool, with beautiful appearance and easy operation.
Features
1. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate, and the shell is sprayed with A3 steel plate. Appearance has good texture and high cleanliness.
2. The replenishment tank is placed in the lower right part of the control box body and has the function of automatic water shortage protection, which is convenient for the operator to replenish the water source.
3. The large observation window is equipped with lighting, and the heating element is embedded with tempered Glass, which can clearly observe the situation in the box.
4. The humidification system piping is separated from the control circuit board to avoid malfunctions due to water leakage and improve safety.
5. The piping circuit system of the waterway system adopts door opening, which is convenient for maintenance and repair.
6. The box body insulation adopts ultra-fine fiberglass insulation cotton to avoid unnecessary energy loss.
7. 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.
8. The temperature and humidity control instrument adopts a 7.0-inch large screen, which is easy to operate, easy to edit the program, supports Chinese and English interfaces and real-time operation Linear dispersion display.
9. With a capacity of 100 sets of programs and 1000 stages of 999 cycles, the MAX Maximum is set to 99 hours and 59 minutes per period.
10. The controller has a screen lock function to avoid human touch shutdown.
11. With RS-232 or RS-485 communication interface, you can design programs on the computer, monitor the test process, and perform automatic switching.
12. With automatic calculation function, it can immediately correct the temperature and humidity change conditions, making the control more accurate and stable.
13. The refrigerator adopts the original French "Taikang" fully enclosed Compressor, and the refrigeration system adopts the unit or binary low temperature circuit system design.
14. Adopt a multi-wing blower for strong air circulation to avoid dead ends and distribute temperature and humidity evenly.
15. The air passage circulates the air outlet and return air design, the wind pressure and wind speed meet the test standards, and the temperature and humidity stabilize quickly at the moment of opening the door.
16. The heating, cooling, and humidification systems are completely independent, effectively reducing testing costs, increasing lifespan, and reducing failure rates.
Principle
The low/high temperature test chamber uses the original French "Taikang" fully enclosed Compressor and unit or binary low temperature circuit system to cool down through the refrigeration system. The heating system uses a nickel-chromium alloy electric heating heater to heat up, and the humidification system works independently. The multi-wing blower is used to strongly circulate the air path to ensure the uniform distribution of temperature and humidity in the test area, and the temperature and humidity conditions are automatically calculated and corrected by the programmable controller to achieve accurate and stable environment simulation.

Steps
Connect the power supply and ensure that the voltage is AC280V +/- 10% or AC380V +/- 10% 50Hz three-phase five-wire.
2. Open the box door and place the test sample on the test rack.
3. Set the test parameters through the large-screen Touchscreen temperature and humidity control instrument, including temperature range, time, etc.
4. Start the equipment and monitor the real-time operation of Linear dispersion to ensure stable temperature and humidity.
5. After the test is completed, turn off the equipment and remove the sample.
Notice
• Operating Environment Temperature should be 5 ℃~ 30 ℃, humidity ≤ 85% R.H.
• Avoid touching the controller screen artificially to prevent unplanned downtime.
• Regularly check the replenishment tank to ensure that the water source is sufficient and avoid triggering the automatic protection of water shortage.
• During maintenance and overhaul, use the water system piping circuit system with door opening.
• Pay attention to safety protection functions, 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.
• The humidification system pipeline is separated from the control circuit board to avoid water leakage failure.
