4 Digits LCD Ultrasonic Thickness Gauge ST5900+ 0.1mm Resolution For Steel Measure 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 and nonmetallic materials such as steel, aluminum, brass,
