INTRODUCTION

Musktool-ETCR3000A+ Digital Earth Resistance Tester adopt 2-wire method, 3-wire method to measure grounding resistance, grounding voltage.

Product features

1.The tester body is light, easy to carry and operate.

2.With the function of judge the auxiliary grounding pile, the tester can display the resistance value of the auxiliary grounding pile during testing, which can avoid the error caused by the excessive grounding resistance of the auxiliary grounding pole.
3.With line resistance verify function, can avoid the error caused by the bad contact of the test line.It makes the measurement of low grounding resistance more accurate and reliable in the field.
4.Grounding voltage measurement function.
