I.Overvview  

HZ1452 SF6 Gas Trace Moisture Tester is an intelligent measuring instrument independently developed by our company. This product is developed and designed according to the national power industry standard DL/T506-2007, using the original imported high-precision dew point transmitter and advanced digital circuit control technology.

The instrument adopts intelligent self calibration technology, bright color display (touch screen), high precision, fast response, free switching of multiple functions, friendly human-computer interaction interface, real-time display of test data and dynamic display of measurement curve. At the same time, the instrument also has an automatic drying tube, which can shorten the measurement time. The instrument has built-in high-capacity rechargeable lithium battery pack, provides ultra long standby time, and is equipped with standard USB interface to export historical data.

The instrument has the advantages of wide measurement range, fast response time, short measurement cycle, intuitive display and convenient operation. It can be applied to the humidity measurement of air, nitrogen, inert gas and any gas without corrosive medium, especially the humidity measurement of SF6 gas. It can be used by departments such as electric power, petrochemical, metallurgy, environmental protection and research institutes, and has a high cost performance ratio.
