The HT-807 is a mechanical tachometer designed for real-time indication of rotational speed in locomotives, industrial equipment, or heavy machinery. It operates without requiring external power, relying on direct mechanical drive to display RPM via an analog pointer. With its rugged construction, high vibration resistance, and long service life, the HT -807 is suitable for harsh operating environments and widely applied in railway and industrial control systems.
