Elcometer 500 [A500C-B] Model B Coating Thickness Gauge. The Elcometer 500 Coating Thickness Gauge accurately measures the thickness of coatings on concrete and other similar substrates* - non destructively. Fast and accurate, the Elcometer 500 Coating Thickness Gauge takes repeatable and reproducible dry film thickness measurements of coatings on concrete up to 10mm‡ thick – without damaging the coating. Taking over 60 readings per minute in standard mode and 140+ readings per minute in scan mode; the Elcometer 500 Coating Thickness Gauge allows users to inspect more coatings in less time. With a choice of intelligent, ergonomic probes, designed for continuous use and field replaceable probe tips you can inspect all day, everyday. The built in signal strength indicator on the Elcometer 500 Coatings on Concrete Gauge prevents false or incorrect readings, as the gauge only displays the coating thickness measurement if the signal strength indicator goes green. Robust, ergonomic and sealed against dirt and water, equivalent to a rating of IP54, the Elcometer 500 Dry Film Thickness Gauge has been designed to work in harsh environments. Incredibly easy to use, the Elcometer 500 Coating Thickness Gauge for concrete can be used in accordance with ASTM D6132, SSPC PA9 & ISO 2808 Method 10. Compatible with ElcoMaster software and ElcoMaster Mobile App, individual coating thickness measurements can be transferred via USB or Bluetooth to PC or a mobile device for analysis and instant report generation.
