1. The studio is made of SUS304 stainless steel and is equipped with a flat reaction handle.
2. The observation window adopts vacuum tempered Glass, which has the function of defrosting, which is convenient for real-time observation.
3. Built-in independent steam humidification system to ensure uniform humidity.
4. Adopt a turbine centrifugal forced air supply system to ensure a more uniform temperature distribution.
5. Using the original imported Compressor, using environmentally friendly R404 refrigerant, with liquid spray chill down and spray liquid defrost function, stable and efficient refrigeration.
6. Built-in pulley design, easy to move.
7. Equipped with imported large-screen LCD touch controller, supports Chinese and English interface, program editing, real-time temperature Linear dispersion display, and has USB3.0 or RS485 interface for remote control.
8. Easy to operate, support fixed-value operation, regular operation and automatic stop.
9. With dedicated function keys for temperature setting, and auxiliary menus to achieve over-rise alarm, deviation correction and menu lock.
10. With multiple safety protection functions, including power-off protection (parameter memory, call recovery), Compressor overload protection, appointment start and stop, circuit self-diagnosis, Sensor fault alarm, upper and lower limit over-temperature alarm, intelligent defrosting, monitoring timing and over-lift prevention device.
Principle
The device uses a multi-stage program temperature control system, using a nickel-chromium alloy heating wire heater and a centrifugal fan to force air circulation (up, out, down) to achieve precise temperature control and uniform distribution. The humidity control generates steam humidification through a stainless steel sheathed heater, which is monitored by imported dry and wet bulb Sensors, combined with an independent steam humidification system to ensure uniform humidity. The refrigeration system uses French Taikang or German BITZER Compressors, and uses environmentally friendly R404A and R23 as refrigerants. Through air-cooled single-stage or cascade refrigeration cycles, with spray cooling down and automatic defrosting functions, rapid and stable cooling can be achieved.
Applications
Reliability test of electronic products, material weathering resistance test, environment simulation of auto parts, Stability assessment of chemical products, storage conditions of pharmaceutical products
Standards
The data did not mention specific compliance criteria.
Steps
Connect the power supply (AC220V +/- 10% or AC380V/415V +/- 10%).
2. Through the large-screen LCD touch controller, select the Chinese/English interface to perform program editing or setting/timing operation settings.
3. Use dedicated function keys to set the required temperature and humidity parameters.
4. Start the equipment, monitor the experimental process through the observation window, and the controller can display the temperature operation in real time. Linear dispersion.
The experiment can be set to stop automatically, or monitored and operated through a remote control interface (USB3.0/RS485).
6. After the experiment is completed, the equipment can be stopped according to the set program.
Notice
• Power supply voltage meets equipment requirements (AC220V +/- 10% or AC380V/415V +/- 10%) before use.
The equipment is equipped with multiple safety protections (such as over-temperature, overload, power-off protection, etc.), but it is still necessary to avoid over-limit operation during operation.
• Pay attention to the water supply of the humidification system. The equipment has water shortage protection, but it is still necessary to ensure that the water source is normal.
• Regularly check the refrigerant status and Compressor operation.
• Use the built-in pulley when moving the device and pay attention to smooth handling.
• Non-professionals should not modify the auxiliary menu settings in the controller at will (such as deviation correction, menu lock, etc.).
• The lead hole of the equipment (inner diameter 52mm) is used for the test wire to pass through. Please pay attention to sealing and safety when using it.
