HUDA QT-E702-408B70 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. The equipment is used for inspection of materials, accessories or instruments under high temperature, low temperature, heat and humidity alternating environment weathering performance and possible damage or life reduction.
1. Box structure: The inner box is made of SUS304 #stainless steel plate, which is acid-resistant, corrosion-resistant and easy to clean; the outer box is also made of SUS304 #stainless steel plate. Equipped with explosion-proof door handle, ultra-fine fiberglass insulation layer, refined silicone rubber door sealing and double-decked vacuum reinforced Glass observation window. The bottom is equipped with a fixed PU movable wheel, and is equipped with a SUS304 #stainless steel sample holder and test hole with adjustable spacing. 2. Refrigeration system: using French Taikang Compressor and American DuPont environmental protection refrigerant (R404a), binary low temperature circuit system design. Temperature and humidity control adopts P.I.D + S.S.R system co-channel coordinated control, with automatic calculation function, accurate and stable control. 3. Heating and humidification system: The heating adopts nickel-chromium alloy high-speed heating wire, and the high-temperature system is independent. The humidification adopts stainless steel tube with built-in nickel-chromium alloy heating wire and high-temperature oxidation mg powder, which has fast reaction and long life. The heating and humidification systems are completely independent and equipped with automatic water replenishment devices. 4. Control system: Adopt precision liquid crystal display programmable temperature controller, smart digital display PID microcomputer temperature control instrument, touch setting, humidity direct display percentage. Temperature Sensor adopts PT100 platinum resistance. With multiple sets of multi-stage programming operation, setting value and program optional, time arbitrary setting function. The main electrical components are "Chint" brand. Equipped with USB data transfer interface and 232 communication interface, can be connected to printer or computer display printing Linear dispersion. 5. Protection system: with overall equipment overheating, fan overheating protection, underphase/inverse phase, refrigeration system overload, refrigeration unit overpressure, overall equipment timing, leakage, operation instructions and automatic shutdown after fault alarm.
The equipment creates and maintains the set temperature and humidity environment in a closed box through the coordinated work of the refrigeration system, the heating system and the humidification system. The refrigeration system uses a binary cryogenic circuit and Compressor for cooling; the heating system raises the temperature through an electric heating wire; the humidification system increases the humidity by generating water vapor through electric heating. The control system uses the P.I.D + S.S.R algorithm and PT100 Sensor for real-time monitoring and feedback, and precisely controls the environment in the box through thermal equilibrate temperature regulation to simulate various temperature and humidity conditions.

1. Move the device to the designated position through the bottom PU activity wheel and fix the casters. 2. Connect the 380V power supply to ensure that the rated current matches the power. 3. Supply water to the humidification system through a front-mounted water supply tank or a fully automatic water supply system. 4. Set the test program or setting parameters through the Chinese/English touch interface, and choose the program mode or setting mode to operate. 5. Place the sample on an adjustable stainless steel sample holder to ensure uniform load-bearing distribution (20 kg). 6. Close the box door to ensure that the refined silicone rubber sealing strip is well sealed. 7. Start the equipment and run the test. The test process can be observed through the observation window. 8. During the test, the computer can be connected through the USB interface or 232 communication interface to monitor, store and playback the temperature and humidity Linear dispersion data in real time. 9. After the test is completed, the equipment is stopped according to the setting and the sample is taken out.
• Power supply voltage is 380V, rated current is 22A, and check for underphase/reverse phase before running the equipment. • Sample placement should be evenly distributed, with a single layer bearing no more than 20kg, and without blocking the circulation of the air duct. • When the equipment is running, do not open the door frequently, so as not to affect the temperature and humidity accuracy and Stability. • Regularly check and clean humidifiers, condensers and other components to ensure humidification and cooling efficiency. • Pay attention to observe the running status of the equipment. In case of over-temperature, overload, leakage and other alarms, the equipment will automatically shut down, and it needs to be troubleshooted before restarting. • The device has a power-off memory function, and the power-off recovery mode (hot start/cold start/stop) can be preset. • Non-professional personnel should not disassemble or repair equipment, especially refrigeration systems and electrical components. • When using the test hole, please use the matching thermal insulation accessories and special sealing soft plugs to ensure the sealing of the box.
