INTRODUCTION

MEWOI4000+ Digital Earth Resistance Tester specially designed and manufactured for the field measurement of ground resistance, adopts digital and micro-processing technology, 3 wire or 2 wire method to measure ground resistance, with unique calibration function for wire resistance, anti-interference ability and environmental adaptability, to ensure the long-term measurement of high precision, high stability and reliability.

MEWOI4000+ Digital Earth Resistance Tester has the unique function of wire resistance calibration, and it is more accurate to measure the low value ground resistance in the field, which can avoid the error caused by the change of wire resistance in the test line for a long time usage.It can avoid errors caused by incomplete insertion of test line into instrument interface or bad contact.It can avoid the error caused by the user to change or lengthen the test line.

MEWOI4000+ Digital Earth Resistance Tester is composed of a host, a current clamp, a test line, etc. It can store 1000 sets of data and has functions such as historical data access, reading, saving, reporting,  printing,and so on.
