The Extech MA445 True-RMS AC/DC Clamp Meter with NCV & Type K Temperature can be used to measure the following electrical and environmental parameters:

  • AC current
  • DC current
  • AC voltage
  • DC voltage
  • Capacitance
  • Resistance
  • Frequency
  • Temperature

This instrument is also capable of performing diode/ continuity tests and duty cycles as well as non-contact voltage measurements. The Extech MA445 True-RMS AC/DC Clamp Meter’s true-RMS capabilities make it suitable for reading non-sinusoidal waveforms; furthermore, its ability to measure DC current makes this clamp meter suitable for automotive applications.

In addition to this, the Extech MA445 True-RMS AC/DC Clamp Meter includes a number of functions optimised for use with various measurement modes:

  • Relative mode for capacitance
  • DC Zero function
  • Data Hold
  • Max/ Min

This instrument also features an Auto Power Off function (which may be disabled if required) and a Low Battery indicator optimised for reducing downtime.

Also adding to the Extech MA445 True-RMS AC/DC Clamp Meter’s practicality is its integrated torch and large, backlit LCD display, making it suitable for use in dark environments.

Finally, the Extech MA445 True-RMS AC/DC Clamp Meter’s 1.2”/ 30mm jaws mean that it can be used to measure conductors up to 500MCM.

The Extech MA445 True-RMS AC/DC Clamp Meter with NCV & Type K Temperature is ideal for measuring a variety of electrical parameters and temperatures. It is suitable for automotive as well as troubleshooting and inspection applications.
