Surface Profile Gauges

Surface profile and roughness gauges measure the texture of a surface. In coating work, they check the anchor pattern left by abrasive blasting so paint will bond; in machining, portable roughness testers drag a stylus across a part and report values such as Ra and Rz.

For blasted steel, check the method and standard your coating supplier names, such as ASTM D4417 or ISO 8503. For roughness testers, compare the measuring range, stylus type, parameters and Bluetooth or data output. Request a quotation from TSA; we ship worldwide, DDP.
