0.1mm Resolution Ultrasonic Thickness Gauge Manual With 4 Digits LCD Ultrasonic Thickness Gauge ST5900+ For metallic and nonmetallic materials ST5900/ST5900+ Ultrasonic Thickness Gauge 1.INSTRUCTION ST5900/ ST5900+ are the miniaturized ultrasonic thickness gauges that can measure wall thickness. ST5900 has a fixed velocity 5900 m/s, which is used only for measuring of wall thickness of steel. ST5900+ is able to adjust velocity so that it can measure the thickness of metallic
