Features of temperature and humidity test chamber
1.High-quality appearance, the body adopts arc shape, the surface is treated with matte stripes, and the flat non-reaction handle is used, which is easy to operate, safe and reliable
2. The rectangular double-layer glass viewing window can be used to observe the test items during the test. The viewing window is equipped with an anti-sweat electric heater device to prevent water vapor from condensing and water droplets, and high-brightness PI fluorescent lamps keep the interior of the box illuminated.
3. It has a test hole for external test power cord or signal line and an up and down adjustable storage tray. Box door Double-layer insulation and tight airtight, which can effectively isolate internal temperature leakage
4. With an external water supply system, it is convenient to supplement the water supply of the humidification barrel, and it can be recycled and used automatically.
5. The compressor circulation system adopts the French "Taikang" brand, which can effectively remove the lubricating oil between the condenser tube and the capillary tube.
6. The controller adopts an imported 7-inch touch screen, which can display the measured value and the set value at the same time. The temperature and humidity test conditions are programmable. The test data supports USB direct export, and the maximum recording time is 3 months.
7. The built-in moving pulley is easy to move and place and has a strong positioning screw to fix the position.
