The M227G Metrahit EX is a compact milliohmmeter for the measurement of low value contact resistance (Ground Bond) in potentially explosive atmospheres. For example, the contacts inside aircraft fuel tanks, or on aircraft outer skins (lightning protection and wick test). This instrument can also be used for general low value resistance measurements inside and outside of potentially explosive atmospheres.
