ACS A1201 – Compact and Precise Ultrasonic Thickness Gauge
The ACS A1201 Ultrasonic Thickness Gauge is a compact and easy-to-use measuring instrument developed for professional ultrasonic thickness measurement (UT) and non-destructive testing (NDT). The instrument is designed for fast and accurate thickness measurement of pipes, tanks, pressure vessels and metal components – even in hard-to-reach areas.
The ACS A1201 measures thicknesses from approx. 0.6 mm to 300 mm and is particularly well suited for inspecting small pipe diameters from 20 mm. Its compact size, low weight and integrated transducer cable make the instrument ideal for field use, working at height and long inspection rounds.
The instrument supports several types of ultrasonic transducers in the frequency range of 4–10 MHz and can be used on both standard steel surfaces and demanding applications such as hot surfaces and corroded materials.
