The SD-CTG301 is a portable coating thickness gauge that measures non-magnetic coatings on magnetic substrates and non-conductive coatings on non-magnetic substrates — the magnetic and eddy-current methods in one unit. It is used across testing, quality inspection and field service.
A 128×64 backlit LCD shows the test method, out-of-limit warning, result, measuring mode and battery status, with 600 values of memory.
