Temp & Humidity SeriesSingle-layer Constant Temperature & Humidity Box
Single-layer Constant Temperature & Humidity Box
• Efficient control system: Adopt high-precision microcomputer without Duan's refrigerant flow control system, control the refrigerant flow by PID method, make the system heating/humidifying and reduce the amount to achieve low energy consumption, energy saving and environmental protection effects. Equipped with intelligent control system for cooling, heating and humidity control, it can keep the equipment working stably for a long time.
• The large observation window with bright and wide field of vision is adopted. The floating LED light keeps the inside of the box bright, and the built-in glass inside the heating body keeps the window surface clear at any time, without the need for wipers and defogging, which is convenient for observing the situation inside the box.
• Convenient and fast automatic water supply system: the water supply box is placed at the bottom of the test box, which is convenient for supplementary water supply.
• The box circuit system, water system and refrigeration system are modularly distributed to ensure safe and reliable operation.
