COATING THICKNESS GAUGE The Elcometer 211, commonly referred to as the "Banana Gauge", has proven to be a successful coating thickness gauge where the use of electronic instruments is difficult, e.g. inflammable atmospheres in oil and gas production. The "V" grooved base, rubber feet and clear scale, with its ranges for thicker coatings, make this one of the most popular mechanical gauges in the world. Factory calibrated - with user calibration adjustment Foils supplied to check calibration on site Ideal for cold surfaces and underwater use Small and portable with an accuracy ±5% Technical Specifications - Elcometer 211 Coating Thickness Gauge Part Number    Description    Range A211F--1M    Elcometer 211 Coating Thickness Gauge    0 - 1000µm A211F--8E    Elcometer 211 Coating Thickness Gauge    25 - 250mils A211F--8M    Elcometer 211 Coating Thickness Gauge    0.65 - 6mm A211F-A1E    Elcometer 211 Coating Thickness Gauge    0 - 40mils Accuracy    ±5% of the reading or ±2.5µm/0.1mil (whichever is the greater) Substrate Thickness    0.4mm (16mils) minimum Measurement Area    30mm (1.18”) Diameter minimum Measurement Diameter    20mm (0.8”) minimum Edge Effects    Must be at least 6mm (0.24”) from edge Dimensions    200 x 60 x 30mm (7.8 x 2.4 x 1.2”) Certificate available    Certificate of Calibration: issued for Fixed Calibration equipment and shows readings and traceability
