AR860 Ultrasonic Thickness Gauge

Ultrasonic thickness gauges use sound wave to measure wall thickness. Different types of materials have different inherent acoustic velocities. (sound travels at different speeds through different materials ).For example the acoustic velocity of steel is 0.2330 inches/microsecond and that of aluminum is 0.2500 inches/microsecond. The unit can be set to any acoustic velocity depending on the material being measured.

    Perfect item, I would deal with them again.Review by charirasu2011
    I use this for my business and it is accurate, the reason i didn't give 5 stars is because i would have liked it to give you even more detail between decimals. (Posted on 11/11/11)
