Electrical multimeters can measure several parameters of a circuit, such as voltage, current, and resistance, and display the findings on a digital screen. Testers also help diagnose electrical issues, test batteries, check circuit continuity, and ensure components function properly.

Electrical Meters & Testers
Digital multimeters and clamp-on meters measure voltage, current, resistance, continuity, capacitance, frequency, duty cycle, temperature, or diode test (clamp-on). Digital displays provide easy-to-read results in even the poorest of lighting conditions. Continuity and cable testers provide a quick, accurate way to detect and test voltage or continuity on wires and cables. A sensor tester determines a sensor's functionality before installation.

Clamp-On Multimeters
Newest Additions!
- Ardent clamp-on multimeters
Ardent clamp-on meters measure AC and DC current up to 1000A/400A, in addition to temperature, frequency, resistance, and more. Certain Ardent meters have a UL listed safety rating of CAT IV 600V / CAT III 1000V.
- Auto or manual ranging
- Rotary clamp jaws allow the user to align the clamp in the orientation of bus bar/conductor while keeping the display and keys facing the user
- Power clamp meters offer True RMS readings along with active, reactive, and apparent power measurements
The Southwire True RMS AC/DC clamp-on meter measures AC and DC current up to 1000A, plus a host of other parameters. This meter has a UL listed safety rating of CAT IV 600V / CAT III 1000V.
- Auto or manual ranging
- Measures AC/DC voltage, resistance, continuity, capacitance, frequency, duty cycle, temperature, and diode test
- Built-in non-contact AC voltage detector and flashlight

(ARD-CM300ACDC)
Voltage Tester
The Southwire 40126N voltage tester provides fast, accurate testing on wires and cables.
- Dual Range 24-600V & 100-600V AC
- Green LED means power on, flashing red LED with beeper means voltage detected
- Low battery self-test
- Two modes: green means high voltage mode, yellow means low voltage mode
- Bright LED flashlight
- Thinner probe tip for working with wall outlets
- On/Off power switch
- Pocket clip for easy storage

Continuity and Cable Testers
The Southwire 40040S tester provides a simple way of checking continuity on wires and cables, and can trace up to three cables at a time. The bright LEDs and loud beeper provide a positive indication of continuity and polarity. Use this tester for correct wiring, opens, shorts, reversals, miswires, split pairs, and shielded cables.
The M550 data/video cable tester gives instant continuity status for Cat 3 through 7a and coaxial cables. This unit features a rugged double-molded tester body and easy-to-interpret LED display.
Both have a detachable remote that allows cables and wires to be tested after installation.

Insulation Tester
New!
The Ardent insulation tester provides precise insulation resistance measurements, ensuring the safety and reliability of devices by detecting insulation weaknesses or failures that could lead to electrical hazards. Additionally, this tester functions as a multimeter with TRMS measuring capability.
- Automatic terminal Blocking System (ABS) prevents incorrect connections, plus blown fuse warning
- Measures up to 3GW with selectable test voltages of 50V to 1000V
- Backlit display, auto/manual ranging, Min/Max function, and continuity testing with an audible signal
- Ensures accurate readings for AC and mixed AC/DC signals, regardless of waveform distortion
