Electrical Safety Testers: Insulation, Milliohm, Earth

Electrical safety testers verify that installations and equipment are safe to operate. Insulation resistance testers check cable and motor insulation, milliohm meters measure contact and bonding resistance with the four-wire method, and earth resistance testers verify grounding systems.

Earth Resistance Testers

Model	Key functions
VC4105A	Earth Reststance Tester, 3 wires Earth Resistance tests, 2 wires simple Resistance tests, Earth voltage test.

VC480C+ Low Resistance Tester, 4 wires testing, Large 0.01m ohm to 2k ohm range, Accurately measure the contact resistance of conductors, electric heating elements and welding points.

VC480C+ microohm (low resistance) tester, adopts four-wire measurement, which effectively subtracts the line resistance of the test line itself to ensure the measurement accuracy. It can test the short-wave nvis antenna resistance test, the voltage equalization ring welding of the building curtain wall lightning protection device, the reliability test of the high-voltage wire erection, the heating components, the wire resistance and the conductor connection resistance of various trains, EMUs and equipment. 2000 digits display
