Product Description

Portable Ultrasonic Thickness Gauge price SA40+ which can test thickness covered with coating


SA40+ is the miniaturized ultrasonic thickness gauges that can measure wall thickness and velocity.


Using new technique of multiple echo(echo-to-echo), SA40+ can measure wall thickness under paint. For a normal ultrasonic thickness gauge, you must remove paint on work piece, but with new SA40+, you can take measurement directly over the paint of work piece and you can get real thickness value of work piece. SA40+ has two measuring modes: normal mode and multiple echo(MEC) mode. By normal mode, SA40+ is a normal ultrasonic thickness gauge; by MEC mode, SA40+ can measure over coatings.
