Extech CG204 Coating Thickness Tester
The Extech CG204 is a portable meter designed for noninvasive coating thickness measurements. The tester uses dual technology that provides automatic recognition of ferrous (magnetic induction measurement) and non-ferrous (eddy current measurement) substrates. Featuring two measuring modes: Single and Continuous, 400 reading memory storage and user-programmable high/low alarms. Comes with two AAA batteries, USB cable, software, calibration iron, calibration aluminum, precision standards, pouch case, and user manual.
