Gossen Metrawatt M227C MetraHit 27AS aircraft suit

Commodity Description

METRA HIT 27AS (M227C) aircraft set Gossen MetraHit 27I & 27AS - aircraft insulation tester, Millohmeter, universal meter and data recorder MetraHit 27I is a million ohm, universal meter and data recorder, set insulation testing ability in one. Metrahit 27AS is an aeronautical test suite, including METRAHIT 27I. METRAHIT 27I and 27AS can be used for a wide range of applications, especially aeronautical technology, field service and maintenance. Application of METRAHIT 27I is an ideal choice for universal low resistance measurement. It can also be applied to contact resistance measurement, riveting joints and other special purposes. METRAHIT 27AS is an ideal choice for voltage, insulation, kilohm and temperature measurement in electrical applications of aircraft or helicopters. It is also an ideal choice for evaluating aircraft skin, used for lightning protection and wick test. 

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.
