4、 Box structure:

The box is made of CNC equipment with advanced technology, smooth lines, and beautiful appearance

The material of the inner box is 1.2mm thick 304SUS stainless steel brushed plate, and the material of the outer box is 1.5mm thick A3 cold-rolled steel plate sprayed with plastic

The insulation material between the inner and outer boxes is ultra-fine glass fiber cotton, which has good insulation effect. The door frames between the inner and outer boxes are connected

Connected to a fiberglass frame, this connection has a good effect

4. Imported sealing materials and unique silicone sealing structure are used between the door and the door frame, which is sealed and has good aging resistance

The 5 door locks adopt the internationally popular light pressure lock, which improves the sealing performance of the box door

The air ducts inside the 6 boxes adopt a dual circulation system, consisting of two long axis axial flow fans, two stainless steel multi wing centrifugal fans, and a circulation system

Air duct composition, with uniform temperature inside the upper air outlet and lower air inlet box, increases high air flow rate, heating and cooling

The ability has greatly improved the temperature uniformity of the test chamber

7. The heater adopts a stainless steel ceramic strip electric heater, which heats up quickly and has a long service life

8) The middle of the box door is equipped with a large area of anti condensation tape conductive film insulated glass window and a high and low temperature resistant lighting device, which can clearly

Observing the experimental items inside the studio

External humidification system with solenoid valve controlling water inlet and liquid level switch controlling water level

The left side of the 10 box is equipped with a 50mm diameter test hole (customizable according to customer requirements), which can be used for external testing power lines or signals

Line usage

5、 Measurement and Control System

The temperature and humidity controller adopts a "TT-5166" large screen LCD display screen (7 inches), which is easy to operate and has RS-

232 communication interface, capable of remote control and software transmission, capable of designing programs on a computer and monitoring the entire testing process,

Save and print experimental data and curve diagrams.

Display resolution: 0.01 ℃
