Overview
DHS-225 low temperature constant heating and humidity box is a ZKHS brand Environmental performance equipment, suitable for aviation, automotive, home appliances, scientific research and other fields, used to test electrical, electronic and Miscellaneous products under high temperature, low temperature, heat and humidity or constant test conditions parameters and performance changes. The equipment adopts advanced refrigeration technology and precision temperature and humidity control system to ensure a stable and reliable test environment.
Features
1. The box is processed by numerical control machine tool, which is beautiful and easy to operate
2. The liner 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, simple operation and easy program editing
4. Large observation window with lighting, double-decked Glass, clear observation
5. Independent temperature limit alarm system to ensure experimental safety
6. Optional recorder and printer, support 4~ 20mA standard signal
7. The left side of the box is equipped with a 50mm diameter test hole
8. Adopt the original French "Taikang" fully enclosed Compressor unit
9. Multi-wing blower with strong air circulation, uniform temperature distribution
10. The heating and cooling systems are completely independent, effectively reducing test costs and failure rates
Principle
The equipment realizes temperature control through a fully enclosed Air-Cooled compression refrigeration system and a nickel-chromium alloy electric heating heater. The built-in isolated all-stainless steel shallow surface evaporative humidifier and evaporator coil dewpoint temperature laminar contact dehumidification method are used to adjust the humidity. The multi-wing blower's strong air circulation ensures uniform temperature distribution in the test area, and the independent temperature and humidity control system realizes accurate environment simulation.
Applications
Aviation, automotive, home appliances, scientific research
Standards
GB/T5170.5-2008、GB/T10586-2006、GB/T2423.1-2008、GB/T2423.3-2006
Steps
1. Connect the power supply (AC220V +/- 10% 50Hz or AC380V +/- 10% 50Hz three-phase five-wire system)
2. Set the required temperature (0 ℃~ 100 ℃) and humidity (30~ 98% R.H) parameters through a 7.0-inch large screen
3. Set the test time (0~ 9999 minutes or hours adjustable)
4. Start the device running
5. Monitor the condition of the box through a large observation window
6. Turn off the equipment after the test is completed
Notice
• Operating Environment Temperature should be in the range of 5 ℃~ 30 ℃
• environment humidity should be ≤ 85% R.H
• Pay attention to check the water supply system to avoid water shortage
• Regularly check the function of the safety protection device
Do not open the door frequently when the equipment is running, so as not to affect the temperature stability
• Power frequency fluctuation range
• Keep equipment well ventilated
