Overview
HUDA QT-E702-225K60 programmable humidity chamber is mainly used to simulate the 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 of its high temperature resistance, cold resistance, heat resistance and possible damage life reduction. The equipment adopts advanced control system and high-efficiency refrigeration system to ensure accurate and stable temperature and humidity control.
Features
1. Box structure: The inner box is made of SUS304 #stainless steel plate, the outer box is Cold rolled steel plate paint, the thermal insulation system is filled with ultra-fine fiberglass, the door sealing is made of silicone rubber, the mobile device is equipped with PU movable wheel, the sample holder can adjust the spacing, the test hole is φ 50mm, and the observation window is double-decked vacuum reinforced Glass.
2. Refrigeration system: using French Taikang Compressor and American DuPont environmental protection refrigerant, temperature and humidity control using P.I.D + S.S.R system, resolution up to 0.1 ℃.
3. Heating and humidification system: Nickel-chromium alloy electric heating wire is used for heating, the humidification system is independent, and the humidity has an automatic water replenishment device.
4. Control system: Precision liquid crystal display programmable temperature controller, support multi-group multi-stage programming, electrical components use Chint brand, with data processing and communication interface.
5. Protection system: including over-temperature, fan overheating, under-phase/reverse-phase, overload, overvoltage, timing, leakage and other protection, automatic shutdown after fault alarm.
Principle
The test chamber uses binary low temperature circuit design and Compressor work through the refrigeration system to achieve temperature control; the heating and humidification system operates independently, using nickel-chromium alloy electric heating wire and automatic water replenishment device to adjust the humidity; the control system uses P.I.D + S.S.R coordinated control and thermal equilibrating temperature regulation to ensure accurate and stable temperature and humidity; the air circulation system is forced to circulate through the centrifugal fan to maintain a uniform environment in the box.
Applications
Electronic Instruments, New Materials, Electrical, Vehicles, Metals, Electronics, 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 and fix the casters.
2. Connect the power supply and ensure that the voltage is 380V.
3. Set the temperature and humidity parameters through the touch screen, and select the program or setting mode.
4. Place the sample on an adjustable sample rack to ensure uniform load-bearing distribution.
5. Start the device, monitor the running status, and use the observation window and data processing interface to record data.
6. After the test is completed, stop the equipment and process the data.
Notice
• Power supply voltage meets 380V requirements to avoid underphase or reverse phase.
• Sample placement should be evenly distributed, with a load-bearing capacity of no more than 20kg.
• Regularly check the refrigeration system and humidification system to prevent overload or leakage.
• When using the test hole, make sure the sealing accessories are in good condition.
• Immediately stop the machine for inspection when the fault alarm occurs to avoid equipment damage.
• Keep the observation window clean to ensure a clear observation of the test process.
