RA-912F Portable SF6 Gas Comprehensive Analyzer

For determining the quality of SF6 gas.SF6 purity analyzer .SF6 Dew point analyzer and SF6 Decomposition product analyzer 3 in 1.

RA-912F allows the determination of up to three quality parameters with only one measurement:

SF6 concentration (%)

Moisture concentration

SO2 concentration (ppm)

1.Using the principle of SF6 gas spectral absorption measurements,

rapid, without the interference of other gas components to better meet the needs of the site.

2.SF6 purity mass ratio (g / g), volume ratio (mol/mol) switch at any time to display

can be directly controlled national standard, eliminating the volume and mass ratio conversion link.

3.Massive experimental data, based on real-time traffic temperature compensation.

4.Unique patented drying protection device.

5.Boot-up zero, the slope of the self-calibration.

6.Built-in gas filtration system

7.Each measuring gas path individually designed to ensure accuracy, independent regulation is more suitable for field use.

8.TFT touchscreen

9.Built-in printer
