Which is a good production circuit resistance tester

HYHL2200 Series Loop Resistance Tester (Color Screen)

HYHL2200 Series Loop Resistance Tester (Color Screen)

oneProduct Overview

According to the requirements of the preventive testing regulations for new power equipment, the conductive circuit resistance test of various switchgear is a mandatory item, and the test current shall not be less than 100A, and the continuous current time shall not be less than one minute. In response to this, our company has designed and developed a new generation of circuit resistance tester series products, which are suitable for testing the contact resistance values of the main contacts of high and low voltage switches, as well as the DC resistance values of high and low voltage cable lines. The 100A circuit resistance tester adopts a 100A constant current output and can use test lines with thinner cross-sections, reducing the labor intensity of on-site testers.large screen7.5-inch color LCD touch screen displayDisplay intuitivelySuitable for different work environments.
