SF6 Analyzing Meter

The SF6 Analyzing Meter is a modern instrument, measuring moisture content in hydrogen, nitrogen, other inert gases and non-corrosive gases, especially SF6 gas, in high precision. It's used in SF6 switches distribution station, hydrogen station and hydrogen-cooling generators, also used in petrochemical and metallurgical industry, environmental protection industry, scientific research institutes and other fields.

The SF6 Analyzing Meter has high precision humidity sensor, high accuracy, repeatability, quick measuring speed and low shifting. It is an ideal choice for low dew point industry environments that need to control dry point.

SF6 Multi-function Analyzer

The SF6 multi-function analyzer is used for successful SF6 gas recycling and reuse, it's essential to detect three main values: purity of SF6 gas, moisture content and concentration of SF6 decomposition products.

The SF6 multi-function analyzer detects those three values providing the best way to reuse the SF6 gas and recycling efforts validation from the worksite. It's able to analyze three values at the same time saving gas and reducing air pollution.

The SF6 multi-function analyzer has a sensor for moisture imported from Finland; another sensor is for purity imported from Germany and finally from England, this imported sensor is for decomposition and is special for SF6 gas.

SF6 Volume Percentage Analyzer

The SF6 volume percentage analyzer is the most advanced meter special for analyzing volume percentage in SF6 gas tank or SF6 switches. A conventional thermal conductivity method for volume percentage detection has a problem caused by temperature drift. However, our new analyzer is not affected by ambient temperature; it was set up for higher precision and better stability.

The SF6 volume percentage analyzer has the most sophisticated micro thermal conductive sensor available in the market with temperature compensation and also checks percentage in a fast and accurate way, lasting over 10 years.
