HUDA QT-E702-150B70 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.; or under high temperature, low temperature, heat and humidity alternating environment, inspection materials, accessories or instruments are resistant to high temperature, cold, moisture and heat performance and possible damage life reduction.
1. The box structure is sturdy and durable: the inner box is made of SUS304 stainless steel plate, which is 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 and refined silicone rubber sealing strip to ensure reliable sealing. 2. Efficient and accurate temperature and humidity control: using French Taikang Compressor and American DuPont environmental protection refrigerant, with binary low temperature circuit system. 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. Independent and reliable heating and humidification system: heating with nickel-chromium alloy high-speed heating wire, humidity system with stainless steel tube built-in heating element, heating and humidification system is completely independent, and equipped with automatic water replenishment device. 4. Intelligent and convenient control system: Adopt precision LCD programmable temperature controller, support multi-group and multi-stage program operation. With USB data transfer interface, it can be connected to a computer to display and print temperature and humidity time Linear dispersion. The main electrical components use well-known brands. 5. Comprehensive safety protection system: with multiple protections such as overall equipment overtemperature, fan overheating protection, underphase/inverse phase, refrigeration system overload, overpressure, timing, leakage, etc. Automatic shutdown after fault alarm.
The equipment creates a set high temperature, low temperature or heat and humidity environment in a closed test chamber through the cooperative work of the refrigeration system, heating system and humidification system. The refrigeration system adopts a binary low temperature circuit design, and the Compressor drives the refrigerant circulation to achieve cooling; the heating system heats up quickly through the electric heating wire; the humidification system generates water vapor through heating to increase the humidity. The precision P.I.D + S.S.R control system monitors the temperature and humidity in the box in real time, and compares the calculation with the set value, and automatically adjusts the output power of each system to achieve accurate and stable control of temperature and humidity, so as to simulate the required test environment.

1. Preparation and placement: move the equipment to the designated position and fix the casters. Adjust the spacing of the sample holder and place the test sample (load-bearing needs to be evenly distributed, ≥ 20kg) on the sample holder. 2. Connection and Settings: Connect the power supply (220V). Set the temperature, humidity, time and other parameters required for the test through the touch screen, and choose to run at a fixed value or program for multiple stages. 3. Run the test: After confirming that the parameters are set correctly, start the equipment to start the test. The test process can be monitored through the observation window. 4. Data recording and export: During the test, the data can be automatically stored on the SD card. After the test, the data Linear dispersion can be exported to the computer for analysis or printing through the USB interface or communication interface. 5. End and clean up: After the test is completed, the equipment stops running according to the program. After the temperature in the box is close to the environment temperature, open the box door and take out the sample. Regularly clean the inside of the box.
• Sample placement should be evenly distributed, the total weight should not exceed the nominal load of the sample holder (≥ 20kg), and the air duct should not be blocked. Before running the equipment, ensure that the water supply system (front-mounted water supply tank) has sufficient water. • Equipment should be installed in a well-ventilated, non-direct sunlight, away from heat sources and flat ground. • After the low temperature or high humidity test, if you need to open the box door, be sure to be careful of condensation or freezing. • Regularly check and clean the condenser, humidifier and other components to ensure the efficient operation of the equipment. • When any malfunction of the equipment is alarmed and automatically shut down, the cause should be identified, the fault should be eliminated, and then restarted. Do not force operation. • Non-professional personnel should not disassemble or repair equipment, especially refrigeration systems and electrical systems. • When using the test hole, please make sure to use the matching thermal insulation accessories and special sealing soft plugs to maintain the stability of the environment in the box.
