SF6 general-purpose tester - SF-II

SF6 general-purpose tester
One instrument for three tests
sunlight readable LCD display
English menu operation
USB interface

I Description

For successful SF6 Gas Recycling and Reuse it is essential to know three impurity values. These are:

• Purity of SF6 Gas
• Moisture Content
• Concentration of SF6 Decomposition Products

This multi-function analyzer can analyze those three values, therefore providing a very convenient way to determine the reusability of SF6 gas and on-site validation of recycling efforts.

This analyzing meter can finish three measurements one time so saving gas used and reducing air pollution.

This meter adopts world famous sensors from overseas. Sensor for moisture is from Finland; Sensor for purity is from Germany; Sensor for decomposition products is from UK special for SF6 gas.
