        • Product Description

          The DT-2859 Photo/Contact Tachometer is a precision instrument designed to measure rotational speed, surface velocity, frequency, and pulse functions in motors and mechanical systems. Combining both photo (non-contact) and contact modes, it provides flexibility across a wide range of industrial and commercial applications—from HVAC fan monitoring to automotive engine checks.

          Built with an LSI circuit and crystal time base, the DT-2859 delivers fast, stable, and high-accuracy readings. Users can switch between measuring frequency, cycle, RPM, linear velocity, and even define custom pulse distances. It also features a USB data output option for connecting to a PC (cable and software sold separately), enabling long-term data storage and analysis.
