These low cost, compact megohmers offer exceptionally reliable readings of electrical insulation resistance. They feature taut band movement for years of trouble free service, even under the most adverse conditions. Hand crank AC type generators provide a rectified DC test potential. In addition there are no brushes to wear out.

Easy-to-read scales are selectively expanded electronically to assure accurate readings over the entire range of the instrument. And the scales have a scale length of 3.75". This is 42% longer than typical competitive testers.

Selected models have a live circuit indicator that indicates the presence of any voltage present before the crank is turned. Other models have fuse protected continuity ranges. A variety of models are available with ranges for potential up to 2,000 VDC and megohm ranges up to 5,000.
