Micro Ohmmeters (DLROs), Insulation and Ground Test Sets

Resistance is one of the fundamental measurements in any electrical system. This is especially true in high voltage or power systems where insulation integrity is critical to security and safety. Whether measuring micro-ohms or Megohms, Electro Rent has the correct instrument for you.

Electro Rent provides a full range of measurement devices from Associated Research, Megger and Vanguard, including digital low resistance ohmmeters (DLROs), ground testers, insulation resistance testers and micro-ohmmeters.

With Electro Rent’s flexible acquisition options you can rent, lease or purchase ohmmeters, insulation, and ground test equipment to meet your short and long-term needs.
