Extech EX470A True RMS Multimeter with IR Thermometer

The Extech EX470A is a 12-function True RMS autoranging digital multimeter with a built-in infrared (IR) thermometer, two professional-grade instruments in a single, field-ready package. Designed for HVAC technicians, A&P mechanics, and MRO professionals, it combines accurate electrical measurements with non-contact surface temperature sensing, eliminating the need to carry a separate thermometer on the job. With a CAT III-600V safety rating and a 4000-count backlit display, the EX470A delivers professional-level performance for aircraft electrical systems, avionics benches, and industrial maintenance.

Key Features

• True RMS measurement for accurate readings on non-sinusoidal waveforms in variable frequency drive and inverter circuits
• Built-in non-contact IR thermometer with laser pointer, measures surface temperatures from -4°F to 518°F (-20°C to 270°C) with 8:1 D:S ratio
• Type K thermocouple input for contact temperature measurements from -4°F to 1832°F (-20°C to 1000°C)
• 12 measurement functions: AC/DC voltage and current, resistance, capacitance, frequency, duty cycle, temperature, diode, and continuity
• 4000-count autoranging backlit LCD with data hold, relative mode, and MIN/MAX recording
• CAT III-600V safety rating with double-insulated test leads
• Includes adjustable tilt stand, protective holster, and velcro hanging strap for hands-free use

Applications

The EX470A is purpose-built for technicians who need both electrical and thermal measurement capabilities in a single digital multimeter. In aviation maintenance, it is used for aircraft electrical system testing, avionics diagnostics, and non-contact temperature checks of electrical components, motors, and engine bay equipment without removing panels. MRO facilities and FBO maintenance teams rely on the EX470A's True RMS engine for accurate measurements on variable-frequency systems and complex aircraft wiring, while the integrated IR thermometer enables rapid thermal surveys of ground support equipment and hangar electrical panels.
