MIS-A Analog Insulation Resistance Tester (CE)MIS-1A, MIS-2A, MIS-3A, MIS-4A
FEATURES
The single and fluorescent scale indicator for 3 ranges insulation measurements enabled easy observation. Especially, useful when working in dark place.Hand free and continuous measurements with custom made switch.
Safe design with built in automatic discharging function for any capacitors present in the circuit.
The voltage in the circuit can be pre-checked without any switch operation for safe insulation measurements.
Compact, light weight and heavy duty rugged case.
