Megohmmeters

QuadTech's megohmmeters include digital megohmmeters, analog megohmmeters, and digital ohm meters suited for calculating insulation resistance testing or high resistance measurements on cable, wire and other components and materials.

Insulation Resistance Testers

For indicating a quantifiable value of resistance of a component's total insulation, an insulation resistance tester is the tool of choice. Applying a test voltage similar to a routine hipot test, the insulation resistance tester instead uses 'direct current' or DC as a testing medium.  The measured voltage and current are used to accurately calculate a component's insulation resistance.
