Extech MA620/MA640 600A True RMS Clamp Meters + NCV is an integrated non-contact voltage detector that quickly checks for the presence of live wires before testing, plus True RMS and 60A and 600A current ranges.
The Extech MA620 and MA640 are 600A True RMS clamp meters that include a built-in non-contact voltage detector with an LED alert. The MA640 model specifically measures DC current, while the MA620 is limited to AC current measurements.
