Introduction: The constant temperature and humidity testing machine, also known as the environmental testing machine, tests the heat, cold, dry and moisture resistance of various materials. For electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products used for testing quality. Features: With a high-quality appearance, the body adopts an arc shape, the surface is treated with matte stripes, and a flat non-reactive handle is used, which is easy to operate, safe and reliable. Rectangular multi-layer glass view window can be used to observe and use the test article in the test. The window has an anti-sweat electric heater device to prevent the condensation of water vapor, and the high-brightness PL fluorescent lamp maintains the illumination in the box. The double seal of the door is air tight and can effectively block the internal temperature leak. With an external water supply system, it is convenient to add water to the humidification tank and automatically recycle it. Compressor circulation system adopts French "Taikang" brand, which can effectively remove the lubricant oil between the condenser tube and the capillary tube. The whole series adopts environmental protection refrigerant (R23, R404, R507). The controller adopts imported LCD display screen, which can display the measured value, setting value and time at the same time. The controller has multi-stage program editing, OUICK or SLOP control for temperature and humidity. The built-in moving pulley is easy to move and place and has a strong positioning screw fixing position.
