019-09, SERVOMOZ R 111515Z JUN 09 replaced the SERVOMEX and Explosimeter, since they are no longer being supported by their respective vendors.
C/926 serves as the ISEA for Servomex Oxygen Analyzer (NIIN 01-101-3079), Explosimeter Model 3 (NIIN 01446-5625), and the Explosimeter Model 5 (NIIN 01-029-9375).
Explosimeter Calibration--If you have a model 2A, 3 or 5 explosimeter, then you probably already know that calibration on board is an issue.
The Servomex oxygen analyzer NSN 9B 6630-01-101-3079 and both of the explosimeters model 3 NSN 9B 6665-01-446-5625, and model 5 NSN 3B 6665-01-029-9375 are no longer supported by their vendors.
Methanometers (explosimeters calibrated for methane), based on the principle of the heat released by the oxidation of methane on a catalytic surface, are in common usage, and provide a much more quantitative measurement than the proverbial canary.
