At Criterion Instruments we have four different models of AC-DC Ohmmeters to choose from, depending on your needs for resistance testing. Ohmmeters are primarily used to troubleshoot any possible electrical issues such as faulty wiring or short circuits, using precise testing and measurement of electrical resistance.

We have digital AC-DC ohmmeters which measure electrical resistance and are easy to use with easy to read digital displays. The ohmmeter can also be connected via terminals to a computer to store any data that is collected during the testing. The models of AC-DC ohmmeters which you’ll find at Criterion Instruments can measure resistance of circuit-breakers, ground connections, bus bars, batteries and relay contacts as well as motors and transformers during heat run testing. Work with our trained experts who can explain the features of our AC-DC ohmmeters and make sure you have the right piece of testing equipment for the job.
