Fluke Insulation Testers & Megohmmeters

Fluke Insulation Testers & Megohmmeters

Fluke testing tools like the Fluke insulation tester allow for better electrical quality control, preventative maintenance, and safety. As electrical current flows, environmental variables, deterioration, and other factors allow some of the current to escape, which can adversely affect mechanical processes. The regular testing of conductor and electrical equipment insulation can ensure that the equipment is working safely and effectively, and can help you identify problems before they lead to incidents. Fluke builds a wide range of insulation resistance testers with a broad spectrum of voltage outputs and other critical features. From manufacturing and regulated utility installations to the special requirements of IETs and QC professionals, Fluke test tools are the industry leader in insulation testing equipment.


Fluke Insulation Resistance Tester Features


  • Extended battery life
  • Versatile memory storage with ease of recall
  • Line voltage safety warning
  • Digital/analog backlit LCD displays
  • Multimeter functionality available
  • Remote probe, test leads, and alligator clips included


How and Where Will Your Fluke Megohmmeter Be Used?


When buying an insulation resistance tester, Fluke ground resistance meter, or any other test tool, it is important to consider both your application and environment. Environmental factors, such as temperature, humidity, exposure to chemicals, your quality control processes, and, of course, the voltage rating of the equipment under test, all play an important role in determining which insulation tester is right for you. Additionally, portability and data logging capabilities should be considered. Standard insulation testers check for failed resistance, but Transcat also offers multifunctional Fluke test instruments that test a number of parameters, including insulation resistance, voltage, capacitance, and temperature. We also carry innovative models from Fluke that perform both DMM checks and electrical testing. This allows for critical verification of non-energized circuits before the testing connection is made. To select the right testing unit:


  • Review the equipment to be tested, including its nominal voltage rating
  • Check the dc insulation resistance test voltage as set by the manufacturer
  • Select an insulation resistance tester that provides the output test voltage required
  • Assess testing environments to choose proper features


Comprehensive Megohmmeter Functionality


Measurement categories are generally used to rate test instruments on their ability to resist a voltage spike, which is applied through a specific resistance. Usually, the higher the CAT rating, the safer and more durable the test instruments are under extreme conditions. Our inventory of Fluke insulation resistance testers offer:

  • Resistance measurements up to 2 TΩ
  • Test voltage selection in 50V steps
  • Test voltages up to 5 kV
  • CAT III 1000 V, CAT IV 600 V safety ratings
  • Capacitance and leakage current measurements
