Extech Clamp-On Meter Quality

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.

Extech Precision Electrical Power Testing

If you’re an electrician, technician or safety professional, Extech has a tester for your requirements. To measure the electrical resistance of insulators, an auto-ranging Digital Megohmmeter will move easily between your applications. The battery-powered electrical testers travel in the hand or case, delivering accurate readings. Data is easily seen on a large backlit display and functionality includes 250, 500, and 1000V test voltages. It offers:

  • Insulation Resistance to 2000MOhm
  • Lo Ohm functionality for connections tests
  • Hands-free operation

In terms of electrical testing, Extech specializes in functionality that enhances operator capabilities. With the MG300, a 1000V Insulation Tester is combined with a true RMS multimeter in one handheld device. A wireless USB interface allows for data transmissions to PCs. The MG300 provides:

  • Large, backlit display
  • 125V, 250V, 500V, and 1000V test voltages
  • Insulation resistance from 0.001MΩ to 4000MΩ
  • Hands-free, data hold, and automatic shutoff features
  • Durable IP67 design

Specialty Extech Meters for Industry Pros
