The Elcometer 500 coating thickness gauge accurately measures the thickness of dry film on concrete and other cementitious substrates. It can read three times faster than other technologies (60+ readings per minute in standard mode and over 140 readings per minute in scan mode) and it only displays a reading when the signal strength indicator goes green. Designed for continuous use, it features a dust- and water-proof design equivalent to IP54. Visit www.elcometer.com.
