The Metrahit 27I Insulation Tester, Milliohmmeter & Multimeter covers both low value milliohmmeter measurements and high value mega ohm insulation resistance measurements. The Metrahit 27I insulation resistance testing range allows for the testing sensitive devices at 50V and less sensitive devices at 100, 250 or 500V. Low resistance measurement are made possible with either the 4-wire Kelvin clips or the optional special spring loaded spiked 4-wire Kelvin probes these are especially suited for the measurement of low resistance electrical joints/contacts on high power bus-bar and switchgear terminations. The data hold feature of the Metrahit 27I can captures up to 1200 test values these values can then be displayed and printed as a report via the download package and Metrawin 10 software. The lowest measurement range is 3.000mΩ with a 0.001mΩ resolution. The Metrahit 27I also measures voltage & Hz, plus temperature via PT100/1000. Optional mains power supply for extended laboratory use. Supplied with free manufacturers calibration certificate
