2013 new constant temperature and humidity box specifications

   Constant temperature and humidity test box , cold and heat shock test box , high and low temperature alternating test box

Constant temperature and humidity test chamber for electronic, plastic products, electrical appliances, instruments, food, vehicles, metals, chemicals, building materials, aerospace, medical ... and other products used for testing quality. This machine is specially designed to test the heat, cold, dry and moisture resistance of various materials. This machine can choose Chinese or English LCD touch screen screen, simple operation, easy program editing. The complete system operation status data, execution and setting program curves can be displayed. An abnormal condition occurs during operation. The screen immediately displays the cause of the failure and provides technical parameters for troubleshooting.

Constant temperature and humidity test chamber features

1. High quality appearance, the body adopts arc shape, the surface is treated by matte stripe, and it is processed by CNC machine tools. It adopts plane non-reaction handles, which is easy to operate, safe and reliable, and beautiful and elegant in appearance.

2. Rectangular multi-layer glass view window, large observation window with lights to keep the inside of the box bright, and the use of double glass, at any time in a clear observation test for the test product, the window with anti-sweat electric heater device to prevent condensation of water vapor, and High-brightness PL fluorescent lamps maintain the lighting in the cabinet.

3. The double seal of the door is air tight and can effectively block the internal temperature leak.

4. With an external water supply system, it is convenient to add water to the humidifying tank and automatically recycle it.

5. Compressor circulation system adopts the French "Taikang" brand, which can effectively remove the lubricant between the condenser tube and the capillary tube and use the environmental protection refrigerant (R23, R404, R507) for the whole series.

6. Korea TIME880 touch type. Fixed conditions can be set time 0 - 999 H, touch KEY BOARD, can be set arbitrarily fixed or alternating with nine-point warning and simple maintenance methods, rising, cooling can be used for slope control, and self-correcting temperature reference Point of function. The temperature sensor adopts DIN PT-100Ω (Platinum sensing). The temperature control adopts PID + SSR system to coordinate and control synchronously, which can improve the stability and life of the control component and interface.

7. With PID automatic calculation function, the temperature and humidity change conditions can be immediately corrected, so that the temperature and humidity control can be more accurate and stable to reduce the inconvenience caused by human settings.

8. In the setting or operation, if there is an error, it will provide a warning signal.
