The M1 Milliohm Meter® has been in industrial use, primarily in aviation, for over fifteen years. It has proven to be a very versatile and reliable test tool, with low maintenance.
The low voltage and current output will not cause ignition of flammable gas, as certified by Underwriters Laboratories per UL 913 standard entitled “Intrinsically Safe Apparatus and Associated Apparatus for use in Class I, II, and III, Division I, Hazardous Locations.” The unit is approved for use in hazardous environments such as in and around aircraft, fuel installations, fuel cells, and gas systems.
It is a highly sophisticated laboratory grade instrument, designed specifically with the field user in mind. Recalibration is not generally needed. The unit comes pre-tested, calibrated and certified directly from the manufacturer. Re-testing and certification schedules will depend on customer regulatory requirements.
The M1 Milliohm Meter® uses a rechargeable 6″C” cell battery pack with special features that extend battery life for many years under normal working conditions and proper care.
