OEM Best Cold Mirror Dew Point Tester Exporters – GDSF-311WP SF6 Dew Point and Purity Tester – HV Hipot

General Information

GDSF-311WP is ideal instrument when it is necessary to test water content and purity of SF6 gas. The core component is DRYCAP series sensors produced by Finland Vaisala company. With professional hardware chips and excellent software algorithms of STMicroelectronics, we have produced a new generation of gas moisture test instrument.

Application

● Moisture monitoring of SF6 gas electrical equipment for electric power
● SF6 gas cylinder gas quality test
● High purity gas manufacturing
● Semiconductor industry dry gas supply
● Research and development use
● Clean room/dry house monitoring
● Metal heat treatment site and laboratory industrial gas humidity detection, such as air, CO2, N2, H2, O2, SF6, He, Ar and other inert gases.

Features

Specification
