About Safety Ratings for Electrical Testing

Multimeters

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

Fluke Multimeters

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

Electronic-Component Testing Meters

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

Pocket-Size Multimeters

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

Pen-Style Multimeters

The smallest digital multimeter we offer. This meter is a portable and convenient way to perform various electrical tests.

High-Accuracy Multimeters

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

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.

Fluke Hazardous Location Multimeters

These Fluke multimeters are rated for environments where hazardous material is present. They take voltage, resistance, and other electrical measurements.

Analog Multimeters

Measure rapidly changing electrical values with an analog display that shows the magnitude and rate of change more easily than a digital multimeter.

Simpson Analog Multimeters

The analog display shows the magnitude and rate of change more easily than a digital multimeter when measuring rapidly changing electrical values. Simpson multimeters are known for their ruggedness and reliability.

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.

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.

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.

Tweezer-Style Electronic-Component Testers

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

Fluke Instrumentation Process Control Multimeters

With this combination loop calibrator and multimeter, check for current control loop issues in PLCs, motors, and fans in addition to taking other electrical measurements. When used as a loop calibrator, the current input as well as the percentage of the input scale is shown on the dual display, giving you quick diagnostic information. Fluke is known for quality and durability.

Water-Resistant Multimeters

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

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 Water-Resistant Multimeters

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

Open-Jaw Multimeters

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 Open-Jaw Multimeters

Run a cable through the open jaw to test current without interrupting the circuit. These multimeters are especially useful for high current measurements and include test leads to perform other electrical tests. Fluke multimeters are known for quality and durability.

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.

Analog Clamp-On Multimeters

Measure rapidly changing electrical values more easily than with a digital multimeter. Convenient for taking frequent high current measurements, the meter has jaws that surround a cable to test current without interrupting the circuit. Use the included test leads to perform other electrical tests.

Fluke Multimeter Accessories

Magnetic Hangers for Fluke Multimeters

Free up your hands while using your Fluke multimeter by suspending it from this hanger.

Carrying Cases for Fluke Multimeters

Insulation Meters

Insulation Testers

Measure electrical resistance as an indication of insulation quality in equipment such as motors, generators, and switchgear.

Hand Tool Insulation Testers

Ensure proper insulation and ground wire continuity in new or repaired drills, circular saws, grinders, and other hand tools. Also known as a hi-pot tester, it checks the quality of a tool's insulation by applying voltage and measuring how much current leaks from the tool.

Hand-Crank Insulation Testers

Turn the crank to generate voltage and measure electrical resistance as an indication of insulation quality in equipment such as motors, generators, and switchgear.
