The Multimeters & Clamp Meters category focuses on the core electrical test tools HVAC technicians rely on to measure voltage, current, continuity, resistance, capacitance, temperature, and more. From everyday service calls to in-depth diagnostics, these instruments help you confirm that components, circuits, and controls are operating safely and within spec.
Here you'll find HVAC-rated digital multimeters, clamp meters for in-line current measurements, combo meters with temperature and capacitance ranges, and accessory kits with leads, clips, and cases. Many options include True RMS, low-Z input, non-contact voltage (NCV), backlit displays, and CAT III / CAT IV safety ratings for residential and light-commercial work.
When selecting multimeters and clamp meters, pay attention to CAT safety rating, True RMS capability, AC/DC voltage and current ranges, temperature and capacitance functions, display resolution, and backlight visibility. Matching the meter to the systems you service most reduces callbacks and helps you work safely around energized equipment.
Pro tip: Keep a dedicated HVAC meter with microamp (µA) range for flame sensor testing and a rugged clamp meter for everyday current checks. Verifying readings with a known-good reference meter periodically helps you trust the numbers you use for diagnostics and commissioning.
Multimeters and clamp meters for HVAC technicians including digital multimeters, clamp-on ammeters, HVAC combo meters with temperature and capacitance, test kits, and replacement leads for accurate electrical diagnostics on air conditioning, heat pump, and furnace systems.
