Product description

Overview

The SMR series pointer type automatic megohmmeter adopts advanced electronic measurement circuits and components, with stable output voltage, wide measurement range, automatic shifting, and intuitive reading. Especially suitable for the power sector, large factories and mining enterprises, measuring the insulation resistance, absorption ratio, etc. of electrical equipment such as power cables, power transformers, generators, and high-voltage switches. It is an ideal product to replace old-fashioned trameggers.
