Overview
Enviro Test Construct`s four wire battery internal resistance tester with ac sinusoidal measurement battery internal resistance tester is a true four-wire internal resistance tester, which can measure the internal resistance and voltage at the same time. It can also be used to measure the resistance. The measurement results are displayed on the same screen. This tester is suitable for battery configuration, battery performance testing, battery screening and other aspects. It is structurally exquisite, easy to carry, and is an ideal electronic testing tool.
