EXTECH MA445 400A True RMS AC DC Clamp Meter NCV

EXTECH MA445 400A True RMS AC DC Clamp Meter NCV

A digital clamp meter called the EXTECH MA445 is intended for measuring electrical parameters in diverse applications. This adaptable and dependable tool comes with a variety of capabilities to help experts with electrical testing and troubleshooting jobs.

Three models to choose from, with or without True RMS and AC or AC/DC Current functions. Choose a True RMS model for accurate readings of non-sinusoidal waveforms, a model with DC Current function for automotive applications, or a model with Type K function when applications require Temperature measurements.

Up to 400 Amps of AC or DC current can be measured using the Extech MA445. It is practical and secures to use, enabling non-contact current measurements using the integrated clamp.

The Extech MA445 features a resistance measurement function that allows for testing and troubleshooting of resistive components
