Product catalog summary
Overview: The document provides a detailed overview of Extech Instruments' range of clamp meters, including the EX800 and EX700 series, full-size general-purpose clamps, mini clamps, specialty clamps, and power clamps. These instruments are designed for various applications such as electrical, HVACR service, plant maintenance, field service, automotive, and power analysis.
EX800 and EX700 Series Clamp Meters: These series include 1000A and 800A clamp meters, respectively. Notably, the EX800 series features a built-in InfraRed Thermometer for non-contact surface temperature measurements, which is crucial for identifying potential component failures. Both series offer rugged, double-molded housings, True RMS, and Peak Min/Max with 1ms Peak Capture for measuring In-Rush Current. They are available in AC only or AC/DC models.
Full-Size General Purpose Clamp Meters: These meters are suitable for AC or DC current measurements up to 2000A. Key features include True RMS, Min/Max, Peak Hold, Audible Continuity, and Data Hold. Jaw sizes vary from 0.7" to 2.36" to accommodate different wire sizes.
Mini Clamp Meters: Ideal for measuring low AC and DC currents, mini clamps are compact and fit into tight spaces. They offer high resolution to 1mA. The 380947 model is suitable for current measurements up to 400A and includes features like True RMS and Min/Max. The 380941 model adds capabilities for Resistance, Frequency, Diode, and Continuity functions.
Specialty Clamp Meters: These clamps are designed for specific applications, such as HVAC. The MA460+ features a dual display for simultaneous current and voltage measurements. The MA100 and MA120 include a built-in Voltage Detector for safety, and the 390974 offers Phase Rotation testing.
Power Clamp Meters: These meters are used when standard current measurements are insufficient. They are ideal for energy efficiency studies, power factor corrections, and distribution system evaluations. The 382068 model includes datalogging capabilities, while the 382095 is a three-phase power analyzer with a graphical display for comprehensive power system analysis.
Conclusion: Extech Instruments offers a wide range of clamp meters to meet various specifications and applications. These tools are essential for technicians needing to perform common measurements in electrical and power systems.

hatever the application, if AC or DC power is used, the current clamp is an indispensable piece of test equipment. In fact, with its voltage and resistance measuring capabilities, its possible to make most of the common measurements with a clamp meter. If a service technician could take just one test tool to a job, it would make sense to bring a clamp meter. With more than twenty different models from which to choose, Extech has the clamp meter to meet your specifi cations. > The latest additions to our clamp meter family, the EX800 Series and EX700 Series consist of 1000A and 800A clamp meters...

Mini Clamp Meters > Mini Clamps are the ideal tools for accurately measuring very low AC and DC current. Smaller in size than traditional clamps, they can fi t into tight spaces and feature high resolution to 1mA. Extech model 380947 is ideal for basic current measurements up to 400A, and comes with an array of features including True RMS, Min/Max, and Selectable Auto Power Off. The 380941 has the added capabilities of Resistance, Frequency, Diode, and Continuity functions. Those working with DC motors and circuits will appreciate the ease of use of the DC-only DC400 meter.
