Extech 382357 Ground Clamp Meter

5.0

This piece of equipment is a must for gathering accurate measurements of grounding electrode systems. We use it to measure grounding & lightning protection systems. The feel of the meter is high-quality. I love the fact that it comes with a calibration device to challenge the readings. I highly recommend this product.
