in the EPFZ301 ?

General Information:
EPFZ301 is 3-in-1 SF6 Gas Dew Point and Purity Tester applied to test moisture, dew point, purity and decomposition products of SF6 gas. The core component of dew point test is DRYCAP® series sensors produced by Finland Vaisala company.


The humidity measurement of EPFZ301 SF6 Gas Dew Point and Purity Tester adopts the resistance-capacitance method, which uses the principle that the electrical parameters of hygroscopic substances change with humidity for humidity measurement. According to this principle, the humidity sensor adopts Vaisala DRYCAP® sensor. The humidity sensor has been used for industrial humidity measurement for nearly 60 years. The perfect combination of high-quality DRYCAP® and intelligent electronic components enables humidity measuring instruments to be successfully used in various extremely harsh industrial environments. Vaisala provides the world with advanced technologies in the field of humidity measurement. The DRYCAP® sensor is accurate and reliable in the full range of measurement, and has excellent long-term stability. It is not affected by dust particles and most chemical pollution, and is very suitable for use in industrial environments.

EPFZ series is widely used in measuring moisture contains of power electric, petroleum, chemical industry, railroad, pesticide, resin, scientific research divisions and etc.
