Testing Tools

Digital multimeters and testing instruments for electrical, HVAC, and maintenance diagnostics. Reliable readings for voltage, current, and resistance checks on the job.

Testing and measurement on or near energized equipment requires following NFPA 70E safe work practices, including proper PPE and approach boundaries. Meters and probes used in electrical work should meet ASTM F1505 insulation ratings. For testing in hazardous or potentially explosive environments, UL 913 covers intrinsically safe equipment requirements.
