R1M-B Handheld Megohmmeter
Brand: TegamThe Model R1M-B Handheld Voltmeter/ Megohmmeter is designed to measure insulation resistance in “live” circuits, which may have voltage present.
It can be connected to 600 V RMS AC or DC without damage, and its mode of operation is automatic. It has no fuse to replace.
The R1M-B will operate after a drop from a height of four feet to a concrete floor.
The R1M-B complies with MIL-PRF-28800, Type III, Class 3, Style E for rugged operational environments and shipboard applications.
These units perform under the extremes of heat, cold, humidity, shock, vibration, and operator abuse.
