MEWOI-ZCL100E Portable Micro Ohm Meter 100A Contact Loop Resistance Tester Contact Resistance for Testing HV Breaker,Circuit resistance tester,Microhmímetro digital portátil até 100 A
INTRODUCTION
The digital low resistance ohmmeter is a new generation of micro-resistance tester based on modern industrial design concepts. The product is a hand-held instrument, small in size and easy to carry with built-in lithium battery for power supply, which is suitable for field use. The “four-wire” current and voltage test method can meet the measurement of low resistances such as high-voltage switches, circuit breakers, and relay metal contacts. |
MAIN FEATURES
| 1，L1. It is lithium battery-powered. More than 600 consecutive tests can be performed on a single charge, and the test process is simple and convenient; |
| 2， The output current is up to 100A, multiple gears are available, and the test range is wide; |
| 3，At 100A test, the longest test time can reach 60 seconds, which meets various applications in the field; |
| 4， With wide range and high accuracy, it can be up to 4mΩ at 50A; |
| 5，It has open circuit protection, overheating protection and other comprehensive protection functions; |
| 6，With 5.0-inch super-large industrial-grade high-brightness color LCD screen, the display can be still clearly visible under strong sunlight; |
| 7，With local storage and USB flash drive storage, it is convenient for data save. |
