Mask constant temperature and humidity pretreatment box

1. Box structure

The constant temperature and humidity test box is processed by CNC machine tool, beautiful shape, novel and use no reverse handle, easy to operate;

The inner tank is made of imported advanced stainless steel (SUS304) mirror plate or 304B argon arc welding, and the outer tank is made of A3 steel plate injection;

Using microcomputer temperature and humidity controller, temperature control and humidity control are accurate and reliable;

Large observation window attached lights keep the box bright, and use double glass, the situation in the observation box at any time;

With an independent temperature limit alarm system, automatically interrupted beyond the limit temperature, to ensure the safe operation of the experiment without accidents;

A 50mm diameter test hole is on the left side of the box.

2. Control system

Constant temperature and humidity test box Japan imported digital display touch button, PID microcomputer SSR temperature controller;

External boiler steam humidifier has energy saving and consumption reduction function, can save 70% energy consumption;

Electrical appliances control main parts use imported well-known brand "Schneider", to better control the temperature;

The insulation system uses ultra-fine glass fiber to fill the insulation area, and the internal and external bile connection parts use non-metal high resistance and low temperature materials, which effectively reduce the temperature conduction;

With the function of automatic calculation, the temperature and humidity change conditions can be corrected immediately to, make the temperature and humidity control more accurate and stable.

Iii. Refrigeration system

The constant temperature and humidity test box cooler adopts the original French "Taikang" fully enclosed compressor;

The freezing system adopts the unit or the binary low-temperature loop system design;

Us "Aigao" dry filter, Taiwan "Guanya" oil separator, Italy "Casto" solenoid valve;

Using multi-wing fan strong air supply circulation, to avoid any dead corner, can make the temperature and humidity in the test area evenly distributed;

Air circuit circulation air return wind design, air pressure and wind speed are in line with the test standards, and can make the door instant temperature and humidity stabilization time is fast;

The completely independent heating, cooling and humidification system can improve efficiency, reduce test cost, increase life and reduce failure rate.

Four, meet the standards
