Overview
HUDA QT-E702-408K70 programmable humidity chamber is mainly used to simulate the severe 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 or life reduction.
Features
1. Box structure: The inner box adopts SUS304 stainless steel plate, the outer box is Cold rolled steel plate paint, equipped with explosion-proof door handle, ultra-fine fiberglass insulation layer, double-decked vacuum heating and defrosting observation window, fixed PU movable wheel and stainless steel sample holder.
2. Refrigeration system: using French Taikang Compressor and American DuPont environmental protection refrigerant, binary low temperature circuit design, P.I.D + S.S.R temperature and humidity coordinated control, precise and stable control.
3. Heating and humidification system: Nickel-chromium alloy electric heating wire is used for heating, and stainless steel tube is used for humidification. The system is independent, fast response and long life, and is equipped with an automatic water replenishment device.
4. Control system: Adopt precision liquid crystal display programmable controller, touch setting, support multi-group and multi-segment program operation, with USB data transfer interface and printer connection function.
5. Protection system: with multiple protections such as overall equipment overtemperature, fan overheating, underphase/inverse phase, refrigeration system overload, overpressure, timing and leakage, etc., fault alarm and automatic shutdown.
Principle
The equipment simulates the required temperature and humidity environment in a closed box through the coordination of the refrigeration system, the heating system and the humidification system. The refrigeration system adopts a binary refrigeration circuit, and the heating and humidification system is independently controlled. The High Accuracy P.I.D controller calculates and corrects the temperature and humidity changes in real time to achieve fast, accurate and stable environment simulation.
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 device to the designated position through the bottom PU activity wheel and fix it.
2. Connect the power supply (380V).
3. Set the required test procedures or set parameters through the touch screen controller.
4. Place the sample on a stainless steel sample holder to ensure uniform load-bearing distribution (≥ 20kg).
5. Close the box door and start the equipment to start the test.
6. The test process can be viewed through the observation window, and data can be recorded and exported through the USB interface or communication interface.
7. After the test is completed, the equipment is stopped according to the setting and the sample is taken out.
Notice
• The rated current of the equipment is 22A, the rated power is 11kw, and it is necessary to ensure that the Power supply voltage is 380V and meet the corresponding power supply requirements.
• The sample load-bearing should be evenly distributed, and the standard sample rack load-bearing capacity should be ≥ 20kg.
• The equipment has multiple safety protections. In case of fault alarm during operation, it will automatically shut down, and it needs to be checked before restarting.
• When using the test hole, the matching thermal insulation accessories and special sealing soft plugs need to be used to ensure the stability of the environment in the box.
• The device has a power-off memory function, and the power-off recovery mode (hot start/cold start/stop) can be preset.
• The humidification system is equipped with an automatic water replenishment device to ensure the normal water supply.
• Main electrical components such as circuit breakers and AC contactors use the "Chint" brand, please pay attention when maintaining.
• Software operating environment requirements are IBM PC compatible machine, CPU above PII, memory above 128M, Simplified Chinese Windows2000 or WindowsXP operating system.
