Shop electrical test equipment for troubleshooting, installation, preventive maintenance and field service applications. This category includes instruments used to measure voltage, current, resistance, continuity, power and other electrical parameters.
Wallco offers electrical measurement tools for industrial maintenance, electrical contracting, HVAC service, facility maintenance and equipment diagnostics.
Electrical test instruments range from general-purpose digital multimeters to specialized clamp meters, insulation testers, power analyzers and electrical safety testers. The correct instrument depends on the electrical parameter being measured, expected range and installation environment.
Important selection factors include AC and DC voltage range, current range, resistance and capacitance capability, true-RMS measurement, accuracy, resolution and electrical safety category. Clamp meters allow current measurement without opening the circuit, while multimeters provide broader measurement capability through test leads and probes.
For industrial and commercial electrical work, always confirm the instrument's CAT rating, maximum working voltage and compatible leads or accessories before use.
