Ⅰ. FEATURES 1.The tachometer uses microcomputer (CPU) technique; anti-jamming technique for contact measurement of rotation speed (RPM), surface speed (m/min), and contact length (m). 2.Wide measuring range and high resolution. 3.Large screen LCD display provides clear reading. 4.White back light guarantee reading in any light environment. 5.Automatically save Max, Min and last value, also save 96 set of continuous data. (The tachometer starts to store data after first reading) 6.Low battery voltage indication. 7.Surface speed wheel with groove to test surface speed or length of wire, cable, or rope conveniently. 8.Smooth housing design, comfortable to hold and use. 9.The instrument is delicate and rugged. It uses the durable, long-lasting components and a strong, light weight ABS plastic housing. Ⅱ.
