Milliohmmeters

Milliohmmeters are devices generally used when measuring low resistance or the conductive characteristics of instruments such as switches, relay connectors, circuit boards, wire and more. Electri-Temp’s goal is to provide our customers with milliohmmeters that not only get the job done but do so with consistent accuracy and dependability.

It has been our commitment to offer our customers the very best that the industry has to offer and in doing so we offer a diverse line of milliohmmeters that are built to last and perform.

When it comes to milliohmmeters, practicality, portability and convenience are especially important. We are dedicated to offering our customers the features and capabilities that are not only helpful, but essential for a variety of applications. In addition, milliohmmeters provided to customers by Electri-Temp and the companies we represent are tested rigorously in order to ensure peak performance in a wide range of situations and job settings. It doesn’t matter if you’re operating your milliohmmeter in the workshop or the field, you can rest assured that it will not only work well straight out of the box but its durability and quality will allow it to continually deliver accurate readings. At Electri-Temp we deliver to you quality products that you can use and never worry about, allowing you to focus on the job and not the tool.

Our milliohmmeters are not only accurate and dependable but competitively priced. Our line of milliohmmetters includes models with specifications and features such as:

0 - 40° C operating temperature in 80% relative humidity

MILLIOHMMETERS ARE LOW RESISTANCE METERS DEDICATED TO MEASURE AN OHMIC VALUE UNDER A DEDICATED CURRENT

They are based on two main circuits: an extremely stable current source + a high impedance and very accurate voltage measurement system for real 4 wire measurement method (also called Kelvin method)
