HVAC Multimeter with Temperature Clamp K-Type Thermocouple

An HVAC-focused multimeter with built-in temperature measurement via K-type thermocouple clamp. Designed for troubleshooting furnaces, air handlers, and condensers — measures voltage, amperage, resistance, capacitance, and temperature from a single tool.

Key Features

  • True RMS for accurate readings on variable-speed HVAC equipment
  • Built-in K-type thermocouple for supply/return air temperature measurement
  • Clamp-on amp measurement up to 400A for motor diagnostics
  • Capacitance reading for testing run and start capacitors in the field

Specifications

  • AC/DC Voltage: 0-600V
  • AC Current: 0-400A (clamp)
  • Resistance: 0-40MΩ
  • Capacitance: 0-100µF
  • Temperature: -40°F to 1000°F (K-type)

What's Included

  • Multimeter with clamp
  • K-type thermocouple probe
  • Test leads
  • Carrying case

Ships same-day from our Houston warehouse on orders placed before 3PM CST.

Frequently Asked Questions

Can I test capacitors with this meter?

Yes, it measures capacitance up to 100µF, which covers all standard HVAC run capacitors (typically 5-80 MFD) and most start capacitors.

Does the clamp measure amps on a running compressor?

Yes, clamp around a single conductor wire to measure running amps (RLA) or locked rotor amps (LRA) up to 400A.

What does True RMS mean and why does it matter for HVAC?

True RMS gives accurate readings on the non-sinusoidal waveforms produced by variable speed drives and ECM motors. Without True RMS, readings on modern HVAC equipment will be inaccurate.

Is the thermocouple accurate enough for superheat and subcooling?

The K-type thermocouple provides ±1°F accuracy, which is sufficient for field superheat and subcooling calculations.
