Structural features:

●The heat insulation is adopted by water jacket and high-quality insulation materials. The inner liner is equipped with air ducts and is equipped with a fan to form forced convection, which improves the temperature uniformity in the box and CO2 Concentration equality.

● CO2 The inspection uses imported first-class infrared waveguide patents and gold-plated probes. Ensure the accuracy of the measurement data, and the sensor life can reach more than 15 years.

● Indoor CO2 The concentration can be at (0 ～20）％Arbitrarily set within the range, and an internal circulation gas filtration device is adopted to prevent pollution and reduce impurities in the gas CO2 Concentration effect. Improve measurement accuracy and cleanliness in the studio. ● When the box door is opened, the fan will be automatically closed and CO2 Intake valve and stop heating of the water tank. Save CO2 Use gas volume and isolate it from the outside world to reduce pollution caused by air ingress. (In order to reduce the temperature flush in the box, 10 after closing the door min Start heating left and right).

● Temperature and CO2 Concentration using microcomputer data analysis and intelligence PID High control accuracy and strong anti-interference ability. Among them, the temperature control uses three probes to control the box temperature, water temperature and door temperature respectively, so that the studio temperature accuracy is high and the fluctuates less.

● Light touch adjustment switch, lightweight and flexible.

● Independent door temperature control reduces the impact of external temperature changes on the studio constant temperature system and prevents frosting of glass doors. ● Natural evaporation and humidification will keep the work room well.

●In-box temperature, CO2 The concentration and the set parameters are displayed digitally. Door heating, water heating, CO2 Air intake, high water level, water shortage, etc. LED The instructions are intuitive and clear.

● It has various protection functions such as overtemperature, water shortage, and air cutoff to ensure the safe operation of the equipment.
