  Temperature and Humidity Verification Box General description

The PR381 type temperature and humidity check box integrates many advanced technologies and is a highly intelligent temperature and humidity check device. The device is mainly used for detecting hair temperature and humidity meter (meter), dry and wet bulb  thermometer, digital temperature and humidity meter and other special temperature and humidity sensors. The indicators meet the  requirements of "JG205-2005 Mechanical Temperature and Humidity Test Regulations" and "JF1564-2016 Temperature and Humidity Standard Box Calibration Specification", reaching the international advanced level.


Temperature and Humidity Verification Box features:

1. It is small in size, and the whole model is beautiful and generous. Mirror stainless steel container was adopted, and four semi-circular corners be cleaned easily.

2. There is double-layer glass window, and it's easy to check out the status in the case

3.This machine can adjust the temperature and humidity control at will. Sensor adopts imported parts.

4.PR381 has full touch screen with integrated operation interface. Intelligent temperature and humidity controller make the temperature and humidity data much more accurate and reliable.

5. The power of the whole machine is not more than 1.5KW.

6. The process of humidification and desiccant is fast, and the time is short for achieving stability.

7. Specially equipped with the wind speed regulator, you can adjust wind speed when you need.

8. With two operating holes, users can put hands into the box to do the adjustment work.

9. Don’t need defrost. It can work for a long time in the 40%-90% range.
