Structural features: 1. Water jacket or air sleeve structure is adopted, and the studio adopts high-quality stainless steel plate; The air duct is built and equipped with a fan to form forced convection, which improves the uniformity of temperature and CO2 concentration in the box 2. When the box door is opened, automatically close the fan (wj-3 simultaneously closes the CO2 inlet valve) and stop heating to reduce the pollution caused by air entry. The temperature is controlled by computer data analysis and intelligent P.I.D, with high precision and strong anti-interference ability.Three probes are used to control the temperature of the box, the water temperature and the door temperature respectively, making the temperature accuracy of the studio high fluctuation small.(the air jacket type is a double probe, and the control box and door temperature are respectively controlled) 3. Light touch adjustment switch, light and flexible.The display and the set parameters are digital display, and the working status is LED 4. Multiple protective functions such as over temperature, water shortage and air breakage to ensure the safe operation of the equipment 5. Use ultraviolet sterilization lamp to reduce pollution 6. Add humidity by natural evaporation to maintain good humidity in the work room Main technical indicators： Exterior material: cold rolled steel plate surface spraying Internal material: stainless steel plate Outside door: cold rolled steel plate surface spray Inside door: tempered glass Thermal insulation: centrifugal glass wool board Temperature control range: + 3 ℃ ~ 60 ℃ at room temperature (temperature 5 ℃ ~ 35 ℃) Temperature control: PID control Heating method: wj-2: water jacket type; Wj-3: water jacket/air jacket Circulation mode in box: air stirring mode Temperature fluctuation degree, plus or minus 0.2 ℃ or less Temperature uniformity: plus or minus 0.3 ℃ or less Timing range: continuous operation without timing or 1-9999min CO2 concentration control range: 0~20% CO2 control mode: wj-2 series: air distribution mode; Wj-3 series: imported infrared sensor solenoid valve switch mode Humidifying method: the humidifying water pan evaporates naturally Sterilization: UV sterilization ultraviolet rays Alarm function: overtemperature alarm, temperature probe damage alarm, water shortage alarm, CO2 concentration alarm (wj-3 series), CO2 cut-off alarm (wj-3 series)
