High Voltage Insulation Tester

Wide test voltage from 250v to 5000v diagnosis function of pi and dar newly designed alligator clip it comes with a tough hard case filter function reduces noise interference for obtaining stable measurement.

High voltage insulation tester. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. The first dc portable insulation tester was developed in 1889 by our founders sydney evershed and ernest vignoles and by 1903 was being sold as a megger insulation tester.

The ir3455 is a 5 range 250v to 5000v digital insulation resistance tester offering up to 10tω of insulated resistance testing. High performance features include bargraph built in memory leak current and voltage testing and dar and pi calculation capabilities to help shorten work time associated with field insulation testing. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. Ir pi dar dd sv ramp breakdown and burn modes capacitance leakage current.

Megohmmeters also known as insulation testers or megger testers measure resistance to determine current leakage and identify faulty insulation.
