Contact Resistance Tester ZWHR-100R

♦Multiple protection function;
♦Intelligent power management technology;
♦High output voltage and wide measurement range.


Product Introduction

Based on IEC Standard to design for high accurate and digital switches testing. 
The instrument adopts high frequency superpower constant current switch power source technology, can test micro ohm contact resistance. Wildly use in varies switch and electric appliance contact resistance test loop resistance test cable wires test weld contact resistance test.
The machine has high accuracy and great stability, which can meet the requirement of electric power supplier department for high voltage switch maintaining and loop resistance tester.

Functional Characteristics

1.The machine can be controlled by the phone using special software so that the test result can save the phone and queried.
2.The machine has multiple Protection function such as overhot of power protection  disconnection protection and outage protection during the test.
3.Intelligent power management technology, save energy to avoid the machine become hot
4.High output voltage and wide measurement range
5.Quickly test, The test current is from high accurancy constant current,which don’t need to regulate manually.
6.The four-terminal wiring method is used to effectively eliminate the influence of the resistance of the test line on the test results.
