Product Description

 

 

 

Product Overview

Hand held loop resistance tester is also called contact resistance tester and high current micro ohmmeter. It is mainly used for high-precision measurement of the contact resistance of circuit breakers and the resistance of cut-off conductors. It can stabilize the output current for a long time, and meets the relevant provisions of dl\t845.4-2004 general technical conditions for resistance measurement devices, Part 4: loop resistance tester. The hand-held loop resistance tester developed and produced by our company is not only small in size and light in weight, but also can output a maximum 100A large current for 60 seconds continuously, which effectively overcomes the disadvantages of "pulse type" power supply that can not work continuously and can not effectively puncture the "oxide film" of the tested object. With fast testing speed and high precision, it is a very ideal intelligent measuring equipment. It is widely used in various test occasions of electrical switches.
