The GM100 Digital Ultrasonic Thickness Meter is an intelligent micro processor controlled digital instrument that that adopts the ultrasonic measuring principle. It offers immediate and precise measurements with a measurement range of 1.20~225.00mm and velocity range of 1000~9999m/s. It can measure thickness of almost any material that conducts and reflects constant sonic velocity. This is an excellent complimentary accessory and solution for ultrasonic flow meters, used particularly for measurement of pipe thickness as otherwise you often cannot manually measure ‘in service’ pipeline thicknesses. But it’s got many other uses in manufacturing, metal processing, commercial inspections and more!
