In addition to vibrating to confirm the presence of voltage, these testers have LEDs that light up to show an approximate voltage level.

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.

These true RMS multimeters take accurate AC measurements regardless of the load type or sine wave shape. This is important for testing electronic devices that draw current in short pulses that can distort the shape of the wave, such as computers and adjustable-speed drives.

Display count is an industry designation and not an actual value. These 6,000-count multimeters show numbers up to 5,999.

Multimeters with calibration certificate include a NIST-traceable document stating that they have passed a test for accuracy.

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

It is average sensing, so it takes accurate AC measurements when testing equipment that has a linear load and draws current in a smooth sine wave, such as standard induction motors.

Display count is an industry designation and not an actual value. This 2,000-count multimeter shows numbers up to 1,999.

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

The connection end on the test leads is a 4 mm banana plug, which is the standard for connecting to a multimeter.

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. They also connect to your network, so you can view and analyze data remotely. Like other power supplies, they convert AC to DC voltage to power electronic equipment. Mount these power supplies onto DIN rails, which are commonly found inside industrial cabinets and electrical panels. All have spring-clamp wire terminals for quick connections that hold firmer than screw-style terminals.

Download the free software to view readings, save historical data, and analyze performance over time. Having all of your data in one place means you can troubleshoot and create predictive maintenance plans without needing to walk the floor and open enclosures to perform inspections. Saving historical data reduces maintenance costs because you can better predict when equipment should be replaced. Set alarm conditions, so you're alerted if a particular reading is too high or low. All power supplies are compatible with common Ethernet communication standards—check on them from anywhere without additional measuring equipment or sensors.

All of these power supplies use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot. They’re also SEMI F47 compliant, so they meet standards for maintaining output voltage when input voltage dips. This is commonly known as voltage sag immunity.

If you exceed the maximum voltage, temperature, or load, these power supplies protect both the power supply and the connected equipment. They also meet the voltage requirements for use in a PELV (protected extra low voltage) circuit.

Rated IP20, these power supplies prevent your fingers from touching internal components and accidentally shocking yourself. They're UL and C-UL Listed, TUV Rheinland Certified, and CE Marked so you know they meet stringent safety standards. With an NEC Class 2 and LPS output, if something fails inside the power supply, these limit the risk of electrical shock.

Maximum output noise is also known as ripple noise. The lower the value, the less interference the power supply creates. For most applications, a value over 100mVpp isn’t a problem. However, when using to power extremely sensitive electronics, such as audio equipment and high-precision measuring and testing equipment, you’ll want an output noise around 5mVpp or less.

Power factor shows how effectively a power supply draws AC power from the main electrical supply. The higher the power factor—up to a maximum score of 1—the lower your operating cost.

Efficiency describes how good a power supply is at converting the AC power it draws from your main electrical supply into DC power. High-efficiency power supplies cost less money to operate and produce less heat, meaning cooler temperatures in your electrical cabinet.

Power supplies with an output peak current briefly boost power above their maximum operating current for starting motors, actuating solenoid valves, and other applications that require a higher starting current than their operating current.

Bits have a different tip at each end and snap into the shaft. A ball detent holds the bit in place. To use as nutdriver, remove the bit and turn fasteners with the shaft, which is also reversible.

Ultra-grip drivers have a multicomponent handle that provides comfort and the best possible grip for achieving maximum torque. Those with a voltage detector safely test for AC voltage without contacting live wires. Light and sound indicators alert you when over 50 volts AC is detected. The detector is attached to the tool’s handle; remove it from the handle to use it on its own. Bits turn eight screw sizes and the shaft three external hex sizes.
