Extech Clamp Meters

With a reputation for instrument reliability, Extech offers AC, DC or AC/DC Clamp Meters. The company’s quality meters are built for safe, accurate and affordable operations. Models are available with True RMS measurements. The brand’s versatile line of mini-clamp meters are designed for high resolution accuracy readings in tighter spaces.

Extech clamp meters give users access to multimeter and current measurement capabilities. Full featured models, such as the 800A, deliver:

  • AC/DC Current and Voltage, Resistance, Frequency, Capacitance, Temperature, Diode, and Continuity
  • Peak function to capture inrush currents and voltage transients
  • A Hold feature to freeze displayed data

The Extech multifunctional clamps feature integrated test tools, such as an infrared (IR) thermometer. Take the EX830. It’s a 1000A clamp-on multimeter with a non-contact IR thermometer instrument inside. The 830’s generous jaw opening works for one or two conductors. Many Extech clamp-ons offer real value, arriving in a complete package with test leads, battery, probe and case.
