MBW 973-SF6

Gas Recovery
The 973-SF6 is equipped with a gas recovery system that stores the sampled gas during the measurement process in its internal storage tank. After completion of the measurement, the stored gas may be pumped back into the original compartment or into another container. Starting and ending system pressures are also measured.

SO2 Measurement
SO2 is the SF6 breakdown component most widely measured throughout the industry. The 973-SF6 can now be specified to include SO2 ppmv analysis together with humidity and SF6 purity. An integrated user replaceable electrochemical SO2 cell with 100 or 500ppmv ranges can be included with new instruments. Older instruments can be upgraded by return to the factory.

Easy, Automated Usage
User configurable via the full color active matrix LCD touch screen, the 973-SF6 may be configured for measurement of humidity, % volume SF6, or both, with either automatic or manually initiated pump back. Using the bi-directional RS-232 communications port, all measurement data may be easily transferred into a PC for electronic storage and report generation.

Verifiable Calibration
Easily check the calibration at any time using the built-in Ice Test function which provides instant verification of system accuracy and integrity.

Connect and Go
The system is supplied ready for immediate use complete with industry standard quick connect fittings and sampling tube.
