About Safety Ratings for Electrical Testing

Pocket-Size Multimeters

Perform a variety of electrical tests with a multimeter that fits in your pocket.

Electronic-Component Testing Meters

This meter manually adjusts to the low ranges needed for testing electronic components such as circuit boards and diodes.

Multimeters

Take current, voltage, resistance, and other electrical measurements.

High-Accuracy Multimeters

For measurements at least twice as accurate as standard digital multimeters, choose this multimeter.

Water-Resistant Multimeters

Perform electrical tests in washdown environments. These multimeters have an IP67-rated housing.

Fluke Multimeters

Rely on the quality and durability of a Fluke multimeter when taking voltage, resistance, and other electrical measurements.

Fluke High-Accuracy Multimeters

These Fluke multimeters provide results at least twice as accurate as standard Fluke multimeters. Fluke is known for quality and durability.

Data-Logging Multimeters

Identify intermittent issues such as voltage spikes and temporary power flow problems—this meter records measurements from electrical tests over time. Review data in real time or save it for future analysis.

Tweezer-Style Electronic-Component Testers

Grasp tiny components on circuit boards and other electronic systems in order to test, identify, and troubleshoot them.

Fluke Insulation Testing Multimeters

Check insulation quality in electrical equipment such as motors and power tools. You can also take other electrical measurements with these Fluke multimeters, known for quality and durability.

Fluke Wireless Remote-Reading Multimeters

A wireless connection transmits electrical measurements from the multimeter to a separate display, so you can take measurements in hard-to-reach or potentially dangerous locations. Fluke multimeters are known for quality and durability.

Fluke Data-Logging Multimeters

Record measurements from electrical tests over time to identify intermittent issues such as voltage spikes and temporary power flow problems. Review data captured by these high-quality and durable Fluke multimeters in real-time or save it for future analysis.

Fluke Water-Resistant Multimeters

For taking electrical measurements in washdown environments, choose the durability and quality of a Fluke multimeter with an IP67-rated housing.

Clamp-On Multimeters

Suitable for testing high current, these multimeters have jaws that surround a cable to test without interrupting the circuit. They include test leads to perform other electrical tests.

Fluke Clamp-On Multimeters

Jaws surround a cable to test current without interrupting the circuit, making these high-quality, durable Fluke multimeters especially useful for testing high current. They include test leads to perform other electrical tests.
