Overview
DHS-100 low temperature constant heat and humidity box is a testing equipment for testing the parameters and performance of electrical, electronic and Miscellaneous products and materials under high temperature, low temperature, heat and humidity or constant test environment. It is suitable for aviation, automotive, home appliances, scientific research and other fields, with precise temperature and humidity control functions.
Features
1. The box body is processed and formed by numerical control machine tool, which is beautiful and easy to operate.
2. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate argon arc welding, and the shell is sprayed with A3 steel plate.
3. Equipped with a 7.0-inch large screen, it is easy to operate and program edit.
4. Large observation window with lighting, double-decked Glass, easy to clearly observe the situation inside the box.
5. Equipped with an independent temperature limit alarm system, the temperature limit is automatically interrupted to ensure the safety of the experiment.
6. Optional recorder and printer, can print setting parameters and temperature and humidity changes Linear dispersion, support 4~ 20mA standard signal.
7. The left side of the box is equipped with a 50mm diameter test hole.
8. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit.
9. Adopt a multi-wing blower for strong air circulation to avoid dead ends and achieve uniform temperature distribution.
10. The air circulation design meets the test standards, and the temperature stabilizes quickly at the moment of opening the door.
11. The heating and cooling systems are fully independent, effectively reducing testing costs, increasing lifespan, and reducing failure rates.
Principle
The equipment is cooled by fully enclosed Air-Cooled compression refrigeration, using a nickel-chromium alloy electric heating heater to heat up, built-in isolated all-stainless steel shallow surface evaporative humidifier to control humidity, and through evaporator coil dewpoint temperature laminar contact dehumidification to adjust humidity. The circulation system uses a temperature-resistant and low-noise air-conditioned motor and a multi-blade centrifugal wind turbine to ensure uniform distribution of temperature and humidity in the test area.
Applications
Aviation, automotive, home appliances, scientific research
Standards
GB/T5170.5-2008、GB/T10586-2006、GB/T2423.1-2008、GB/T2423.3-2006
Steps
Connect the power supply to ensure that the voltage meets the requirements of AC220V +/- 10% or AC380V +/- 10% three-phase five-wire system.
2. Turn on the device and use the 7.0-inch large screen controller to set the temperature and humidity parameters.
3. Edit the program as needed, and set the test time range to be adjustable from 0 to 9999 minutes or hours.
4. Start the equipment, observe changes in temperature and humidity, and monitor the conditions in the box through a large observation window.
5. After the experiment, turn off the device and disconnect the power supply.
Notice
• Operating Environment Temperature should be between 5 ° C and 30 ° C with humidity not exceeding 85% R.H.
• Power frequency stability to avoid overvoltage or undervoltage operation.
• Regularly check safety protection devices, including leakage, short circuit, over temperature, water shortage, motor overheating, Compressor overvoltage, overload and overcurrent protection.
• The humidified water supply system adopts automatic control to ensure that the water source is normal.
• Avoid opening doors frequently when the equipment is running to maintain a stable temperature.
When cleaning and maintaining, please disconnect the power supply and use the appropriate tools.
