Electrical & Signal Testers

Electrical and Signal Testers for Wiring, Power and Cable Checks

Electrical and signal testers are handheld instruments used to read, trace or check electrical and network connections. This collection covers voltage measurement, outlet checks, power metering, electromagnetic field readings and cable work.

Main product types

• Voltage and power: the VoltSage digital voltage meter reads voltage, and the WattSage wattmeter measures the power drawn by a plugged-in device.
• Outlet checks: the OutletIQ socket tester plugs into a wall outlet to check its wiring status.
• EMF tools: the FieldSentinel EMF detector, WaveGuard Pro EMF reader and FieldSentry EMF meter are used to read electromagnetic field levels around appliances and wiring.
• Cable and fiber: the WireSight network cable tracker helps trace network cabling, and the PhotonTrace Pro visual fault finder is used to check fiber optic runs.

What to compare

Start with the task: voltage reading, outlet testing, power metering, field measurement or cable tracing each call for a different instrument. Compare the display type, measurement range, power source and whether the unit is pocket-sized or needs a bench. For EMF tools, check which field types and units each model reports. For cable tools, confirm the connector types match the cabling in use.

Typical use settings

Homeowners and renters use socket testers and wattmeters around the house. Electricians, installers and technicians carry voltage meters and cable trackers on job sites, while hobbyists use EMF meters for workshop and garage surveys.
