AR~ 860 ALAT UKUR KETEBALAN PLAT ULTRASONIC THICKNESS GAUGE

081385999849 Ultrasonic Thickness Gauge AR- 860 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. The instruction book includes a table of acoustic velocities for common materials. Even if you don’ t know the acoustic velocity or your material, you can measure it with the sample of material of known thickness to start with.
