General Information:
EPFZ-301 integrates SF6 dew point tester, SF6 purity tester, and SF6 decomposition product tester into one, and concentrates the functions that can only be achieved by three instruments on one instrument. One on-site measurement can complete the detection of two indicators, which greatly saves the gas in the equipment. At the same time, the workload of users is reduced, and the work efficiency is greatly improved.
The humidity measurement of EPFZ-301 Automatic SF6 Gas Analyser 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.
