Overview
HUDA QT-E702-1000K70 programmable humidity chamber is mainly used to simulate the harsh high temperature, low temperature or heat and humidity environment that may be encountered during transportation, storage and use of electronic Instruments, new materials, electricians, vehicles, metals, electronic products, aerospace materials, etc., inspection materials, accessories or equipment High temperature resistance, cold resistance, moisture and heat resistance performance and possible damage life reduction.
Features
1. The box structure is sturdy and durable: the inner box is made of SUS304 stainless steel plate, the outer box is Cold rolled steel plate paint, and the thermal insulation system is filled with ultra-fine fiberglass, and the sealing is reliable.
2. Efficient and accurate refrigeration system: using French Taikang Compressor and environmentally friendly refrigerant, binary low temperature circuit design, temperature and humidity control using P.I.D + S.S.R system, accurate and stable control.
3. Independent heating and humidification system: heating using nickel-chromium alloy electric heating wire, humidification using stainless steel tube built-in electric heating wire, the system is independent and fast response time, long life, equipped with automatic water replenishment device.
4. Intelligent control system: Adopts precision liquid crystal display programmable temperature controller, supports multiple sets of multi-segment programming, has data processing function, can be connected to printer or computer, data storage and playback.
5. Comprehensive safety protection: with multiple protections such as overheating of the overall equipment, overheating of the fan, underphase/inversion, overload of the refrigeration system, overpressure, timing, leakage, etc., and automatic shutdown after fault alarm.
Principle
The equipment simulates and precisely controls the required temperature and humidity environment in a closed test chamber through the coordination of the refrigeration system, the heating system and the humidification system. The control system adjusts the power output of refrigeration, heating and humidification through the P.I.D algorithm according to the set program or fixed value, and uses forced air circulation to ensure uniform temperature and humidity in the box, so as to test the tested items for environment Reliability.
Applications
Electronic Instruments, New Materials, Electrical Products, Vehicle Parts, Metal Products, Electronic Products, Aerospace Materials
Standards
GB2423.1-2008/IEC6008-2-1-2007、GB/T 2423.2-2008、GJB150.3A－2009、GJB150.4A－2009、GB2423.22-2008、GBT 2424.5-2006、GB/T 10589-2008、GB/T2423.3-2008(IEC68-2-3)
Steps
1. Move the equipment to the designated position and fix the casters.
2. Connect the power supply (380V) to ensure good grounding.
3. Set the test program or set parameters (temperature, humidity, time, etc.) through the touchscreen.
4. Place the sample on an adjustable stainless steel sample holder to ensure uniform load-bearing distribution.
5, close the door, make sure the sealing is good.
6. Start the equipment and start the test.
7. Linear dispersion can be observed through the observation window during the test, or connected to the computer through the Interface to monitor.
8. After the test is completed, the equipment is stopped according to the program and the sample is taken out.
Notice
• The equipment should be placed on a well-ventilated, non-direct light, flat ground away from heat sources.
• Power supply voltage 380V, rated current 32A, and equipped with a suitable circuit breaker.
• Sample placement should not block the air duct, and the total weight should be evenly distributed and not exceed the load-bearing limit of the sample holder.
• When the equipment is running, do not open the box door frequently, so as not to affect the temperature and humidity accuracy and Compressor life.
• Regularly check the automatic water replenishment device to ensure that the humidification water is sufficient and clean.
• The equipment has multiple safety protections. If there is a fault alarm and shutdown, please troubleshoot it before restarting.
• Non-professionals should not disassemble or repair equipment, especially refrigeration and electrical systems.
• When not in use for a long time, the power should be cut off and cleaned and maintained.
