Engine Tachometer NTCH-200

Engine Tachometer NTCH-200 is a non-contacting type tachometer. Which is easy to measure the rotational speed just by bringing the detection head close to the high-tension wires of gasoline engines. It consists of two type parts, partitioned by a colon left part is for 2 circles engines and the right part is for 4 circle engines as follows. The engine type selected will be displayed on the display and memory storage is inputted in this device.
