Overview
HUDA QT-E702-225B70 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.; or under high temperature, low temperature, heat and humidity alternating environment, inspection materials, accessories or instruments and equipment resistance to high temperature, cold, moisture and heat performance and possible damage life reduction.
Features
1. Box structure: The inner box is made of SUS304 stainless steel plate, the outer box is made of SUS304 stainless steel plate, the thermal insulation system is filled with ultra-fine fiberglass, the door sealing is made of silicone rubber, and the observation window is double-decked vacuum reinforced Glass and heated to defrost.
2. Refrigeration system: using French Taikang Compressor and American DuPont environmental protection refrigerant, binary low temperature circuit system design, temperature and humidity control using P.I.D + S.S.R system with channel coordination control.
3. Heating and humidification system: Nickel-chromium alloy high-speed heating wire is used for heating, and nickel-chromium alloy high-speed heating wire is built into stainless steel tube for humidification. The heating and humidification system is completely independent, and the humidity has an automatic water replenishment device.
4. Control system: using a precision liquid crystal display programmable temperature controller, touch setting, with program testing, multiple sets of multi-segment programming, data storage and transfer (such as USB interface) and other functions.
5. Protection system: with multiple protections such as overheating of the overall equipment, overheating of the fan, underphase/inverse phase, overload of the refrigeration system, overpressure, timing, leakage, etc., and automatic shutdown after fault alarm.
Principle
The equipment works together through the refrigeration system (France Taikang Compressor and environmentally friendly refrigerant), the heating system (nickel-chromium alloy electric heating wire) and the humidification system (stainless steel humidifier) to precisely create the required high temperature, low temperature or heat and humidity environment in the closed box. The control system adopts P.I.D + S.S.R co-channel coordinated control and thermal equilibrate temperature regulation, monitored by High Accuracy Sensor (such as PT100 platinum resistance), and uses forced air circulation to ensure uniform temperature and humidity in the box to simulate and test the performance of the product under specific environment conditions.
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) and check the electrical system.
3. Supply water to the humidifier through the front water tank or automatic water supply system.
4. Set the test program (program mode) or set the fixed value (fixed value mode) on the precision LCD touch screen controller, allowing for multiple sets of multi-stage programming.
5. Place the sample on an adjustable spacing SUS304 stainless steel sample holder to ensure uniform load-bearing distribution (≥ 20kg).
6. Close the box door and ensure that the silicone rubber sealing strip is well sealed.
7. Start the equipment and run the test.
8. The test process can be observed through the observation window, or the computer can be connected through the USB interface and communication interface for data monitoring, storage and Linear dispersion printing.
9. After the test is completed, the equipment is stopped according to the setting and the sample is taken out.
Notice
Samples should be evenly distributed on the sample rack, and the load-bearing capacity should not exceed the specified value (20 kg evenly distributed).
• Before the equipment runs, ensure that the water supply system is normal to avoid dry burning of the humidifier.
• The equipment has multiple safety protection functions. In case of fault alarm, it will automatically stop, and it needs to be checked before restarting.
• When using the test hole, use the attached special thermal insulation accessories and sealing soft plugs to ensure the stable environment in the box.
• The main electrical components of the equipment, such as circuit breakers and AC contactors, use designated brands, please pay attention when maintaining.
• When the power supply is restored after the equipment is powered off, the power failure recovery mode (hot start/cold start/stop) can be set as needed.
• Do not frequently open and close the box door when the equipment is running, so as not to affect the temperature and humidity accuracy and Stability.
