About Extech

Extech Instruments was founded in 1971 and is now part of the Teledyne FLIR family. The catalogue covers a broad range of professional grade test instruments at price points below FLIR's flagship line, while sharing engineering and quality standards.

Product Range

  • Clamp meters. True RMS AC and AC/DC models with auto ranging and inrush capture.
  • Moisture meters. Pin and pinless models for wood, drywall and concrete.
  • Thermal imagers. Entry level to mid range FLIR powered cameras.
  • HVAC instruments. Manometers, anemometers and combustion analyzers.
  • Air quality. CO2, formaldehyde and particulate meters.

Who It Is For

HVAC technicians, electricians, home inspectors, building science professionals and industrial maintenance teams. Extech instruments are professional grade without the premium pricing of high end FLIR thermography or Fluke electrical instruments.

Browse Extech in the relevant categories: clamp meters, moisture meters and thermal imagers.

Frequently Asked Questions

Is Extech the same as FLIR?

Extech is a brand within Teledyne FLIR Systems. The Extech line targets professional trade work at competitive pricing. The flagship FLIR brand focuses on thermal imaging and high end industrial instruments.

What is the warranty on Extech instruments?
