TM290 High Precision Ultrasonic Thickness Gauge with 0.001mm Resolution and A/B Scanning

TM290 High Precision Ultrasonic Thickness Gauge Product Overview TM290 is a new type of handheld high-precision digital ultrasonic thickness gauge with A/B scanning. It adopts the principle of ultrasonic thickness measurement based on pulse reflection. It is suitable for the measurement of material thickness that can make ultrasonic wave propagate in it at a constant speed and get the reflection from its back. The measurement resolution is 0.001mm and the measurement range is
