Gossen Metrawatt M227B offre

In addition to a milliohmmeter and a multimeter, an insulation tester has been integrated into the MetraHit 27I for measurements up through the gigaohm range.

Especially where service and repairs in the field of aviation technology are involved, the instrument can be used in a broad range of applications.
