HUDA NBC-E702-100K40 programmable constant temperature and humidity testing machine is mainly used to simulate the harsh high temperature, low temperature or heat and humidity environment that may be encountered in the 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. 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 strengthened Glass observation window, fixed PU movable wheel and adjustable stainless steel sample holder. 2. Refrigeration system: using imported Compressor and DuPont environmental protection refrigerant, binary low temperature circuit system design, temperature and humidity control using P.I.D + S.S.R system co-channel coordination control, with automatic calculation function. 3. Heating and humidification system: Nickel-chromium alloy high-speed heating wire is used for heating, and nickel-chromium alloy 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 precision liquid crystal display programmable temperature controller, smart digital display PID microcomputer temperature control instrument, touch setting, can do multiple sets of multi-segment programming operation, with USB data transfer interface and communication function. 5. Protection system: with overall equipment overheating, fan overheating, underphase/inverse phase, refrigeration system overload, refrigeration unit overpressure, timing, leakage and other protection functions, automatic shutdown after fault alarm. 6. Main electrical components such as circuit breakers and AC contactors use the "Chint" brand.
The equipment precisely simulates and controls the required temperature and humidity environment in a closed test chamber through the cooperative work of the refrigeration system, the heating system and the humidification system. The control system adopts the thermal equilibrate temperature regulation method, and the temperature and humidity are coordinated and controlled in the same channel through the P.I.D + S.S.R algorithm to achieve fast and accurate temperature and humidity adjustment. The refrigeration system adopts a binary low temperature circuit design, which is convenient for different temperature domains to use different Compressors for work. The humidification system is isolated to ensure the independence and stability of humidity control.

1. Move the device to the designated position through the bottom PU activity wheel and fix it. 2. Connect the power supply (single-phase 220V). 3. Set the required temperature, humidity and program parameters through a precision liquid crystal display programmable controller. 4. Place the sample on an adjustable stainless steel sample holder to ensure uniform load-bearing distribution (standard load-bearing capacity of 20kg). 5, close the door, make sure the sealing is good. 6. Start the equipment and start the test. 7. The test process can be observed through a double-decked vacuum-strengthened Glass observation window. 8. After the test, stop running through the controller and remove the sample. 9. You can use the USB interface or communication interface to connect to the computer for data transfer, display, and printing.
• Samples should be evenly distributed according to the standard load of 20kg. • Make sure the box door is sealed before the equipment runs. • Pay attention to the protection system alarm when the equipment is running, and the equipment will automatically shut down after the fault alarm. • When using the test hole, use the included special thermal insulation accessories and sealing soft plugs. The equipment is equipped with an automatic water replenishment device, but the water supply system still needs to be checked regularly. • The main electrical components are designated brands, and it is recommended to use products of the same specifications when maintaining and replacing.
