Fluke 1507 Digital Megohmmeter Insulation Resistance Tester
  • Repetitive or hard-to-reach testing is easy with the remote test probe
  • Live circuit detection prevents insulation test if voltage greater than 30-Volts is detected for added user protection
  • Read measurements easily with large, backlit display

The Fluke 1507 is one of those resistance testers that are designed for all skill levels. It’s multiple testing ranges makes it the recommended tool for many commissioning, preventative, and troubleshooting applications.

The Fluke 1507 digital multimeter can perform both basic and advanced functions for electricians. Electricians can make simple repetitive tests with the use of the Pass/Fail function. Other important features include an automatic shutoff feature to conserve battery power, live circuit detection that prevents testing if the subject material is over 30 volts and automatic calculation of Dielectric Absorption Ratio and Polarization Index.

In-depth Review of the Fluke 1507

Performance is important when getting your first insulation resistance tester. The Fluke 1507 comes with a remote test probe that makes hard-to-reach testing easier. With its multi-test voltages, it can be useful for many commissioning, preventive maintenance and troubleshooting applications.

There are several different modes that are available for testing. For instance, there is a pass/fail mode for beginners and a complex set of readings for more experienced electricians. Users can test the AC/DC current, diode testing, and simple voltage testing, making it a versatile tool that can be used for most environments.

Another one of its selling points is its automatic calibration of the Dielectric Absorption Ratio and Polarization Index. This saves the electrician both time and money by giving them the tools needed to measure high voltage areas safely and effectively.

Whether you work on cables, switch gears, generators, motors, the Fluke 1507 provides noise-free and reliable results. It can test resistance up to 1000 V range, giving professional electricians the tools needed to work on commercial appliances.

Fluke 1507 vs 1587

When in the market for a Fluke 1507, you’ll inevitably ask yourself the question – what’s the difference between a Fluke 1507 vs Fluke 1587? The simple answer is that the Fluke 1587 is an upgraded version of the Fluke 1507.

Here are the main differences when comparing the Fluke 1507 vs 1587:

  • The Fluke 1507 does not allow for capacitance, frequency, or diode testing
  • The Fluke 1507 does not allow for temperature measuring
  • The Fluke 1507 does not include a low-pass filter to block unwanted voltages when measuring AC voltage and AC frequency
  • The Fluke 1507 does not allow for True RMS meter readings (the Fluke 1587 does)
  • The Fluke 1587 includes an optional magnetic hanging system

These features account for the difference in price between the Fluke 1587 and the Fluke 1507 (the Fluke 1587 is more expensive). If these are features you need, then you should buy the Fluke 1587 instead. If you need more information on the 1587, see our in-depth Fluke 1587 review, or alternatively read our comprehensive guide on the best insulation resistance tester.

Build Quality

The Fluke 1507 has a rugged build quality, meaning that it can sustain itself through a busy week where it will be frequently used. It features a live detection circuit that prevents an insulation test if the detected voltage is above 30 Volts. And it has a IP rating of IP40, which keeps it safe from small wires under 1 cm. This provides more user protection, making it a great choice for professionals and hobbyists alike.

Display and Labels

With its large backlight screen, users can read their measurements with ease. The labels on the device can be viewed easily, which helps when testing for the right unit. The buttons are large enough to be seen and can be pressed to run the proper testing.

Function and Performance

The Fluke 1507 can test resistance at a range of 10 gigaohms. It can perform testing on the voltage or its own battery. Since it has a large resistance range, users will have no problem deciding if their tested materials are insulated or not.

Protection

There is a warning light placed on the right side of the Fluke 1507. Once the light flashes red, it means that the equipment has excess voltage. This allows electricians to remain safe by telling them when the tested material is over 30 volts and could potentially be a hazard.
