Digital Ultrasonic Thickness Gauge With 4 Digits LCD Backlight 1000 - 9999m/S Velocity
Handheld Ultrasonic Thickness Gauge SA40+ which can test material thickness covered with coating
Using new technique of multiple echo(echoto-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(ME) mode. By normal mode, SA40+ is a normal ultrasonic thickness gauge; by ME mode, SA40+ can measure over coatings.
Measuring Principle
The ultrasonic sent out by the probe reaches the object to be measured through couplant and reflects back from its back surface. The probe receives the ultrasonic reflected and gets the thickness of the object to be measured through calculating the time of ultrasonic reflecting back.
