Measure current without interrupting the circuit—jaws surround a cable for testing, making these meters convenient for taking frequent measurements.

Measure the amount of power your devices draw and calculate energy costs with these consumption meters. Plug them directly into an outlet, and plug your tool or appliance into the front of the meter. To track your power costs, enter the local price per kilowatt-hour (kWh) into the meter, and they’ll display the total amount you’re spending. They also help you monitor the quality of electricity coming from your outlet.

These meters meet U.S. and international safety standards. Rated CAT II, 150V, they can be safely used with most single-phase AC appliances and tools.

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.

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.

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.

Diagnose problems with analog and digital telephone lines.

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

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

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

These Fluke multimeters are rated for environments where hazardous material is present. They take voltage, resistance, and other electrical measurements. Multimeters have durable sealed housing and are rated IP67 for protection from washdowns and temporary submersion.

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.

The smallest digital multimeters we offer. These meters are a portable and convenient way to perform various electrical tests.

Protect electrical equipment from overcurrent and undercurrent damage—these relays continuously monitor current flow. When current is outside a set range, they trip and cut power to prevent overheating, fire hazards, and stalling. Rated IP20, these relays have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

Detect and mitigate ground faults to prevent harm to equipment, circuits, and people. These relays monitor the differential between incoming and outgoing current, also known as residual current. When the balance is off, they trip and cut power to the circuit. These relays are highly sensitive, so you can trust them to de-energize faulty circuits before a minor issue becomes a major one. Rated IP20, they have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

These relays require a current-indicating ring (sold separately) to operate. Choose a ring that is large enough for your lines to pass through. Feed the lines of the circuit through the center of the ring and connect the indicating ring output to the relay.

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

Monitor phase, voltage, and frequency at the same time to protect motors, generators, and other three-phase circuits from burning out or overheating. They'll switch the circuit off if they detect voltage or frequencies outside of the set range or phase loss, imbalance, or reversal. Rated IP20, they have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

These relays use IO Link, so they can be programmed, monitored, and reset remotely by connecting them to a programmable logic controller (PLC), human-machine interface (HMI), or computer. If you want to program them locally, they have a keypad.

Perform a variety of electrical tests with multimeters that fit in your pocket.

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

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.
