Motor Voltage Monitors

DIN-Rail Mount Motor Voltage Monitors

Mount these monitors to DIN rail.

Surface-Mount Motor Voltage Monitors

Use the mounting holes to attach monitors to a flat surface.

Socket-Mount Motor Voltage Monitors

Plug monitors into relay sockets for fast installation and replacement.

Electrical Testing

Voltage and Current Loggers

Record data over time to monitor energy consumption and troubleshoot intermittent problems such as voltage spikes. These loggers connect to a computer to download data for later analysis.

Fluke Scopemeters

Perform electrical tests, record data, and see a graph of electrical waveforms with this combination multimeter and oscilloscope. Fluke scopemeters are known for quality and durability.

Analog Panel Monitors

Observe rapidly changing electrical values in equipment such as motors and generators with an analog display that shows the magnitude and rate of change more easily than a digital display.

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.

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.

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.

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.

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.

Water-Resistant Multimeters

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

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.

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

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 Test Sensors

Take temperature readings with a Fluke multimeter.

Fluke Test Lead Kits

These kits include a set of red and black Fluke test leads with a variety of interchangeable tips.

Status-Indicating DIN-Rail Power Supplies

Monitor voltage, current, remaining life, and other maintenance data from your PC, PLC, or by glancing at the digital display. There's no need to inspect these power supplies with multimeters or other test equipment.
