Three tachometers expand options for gathering condition-monitoring data.
Models TKRT 21 and TKRT 31 are digital units, while the TKRT 25M is mechanical. All are compact, have large displays, and can be operated with one hand. The TKRT 21 uses laser or contact measurement to determine rotational and linear speeds, allowing measurement at a safe distance from machinery. The instrument offers high speed and distance versatility in several measurement modes. TKRT 31 is more advanced and measures rotational and linear speeds and distances. The TKRT 25M mechanical version uses precise contact measurement to determine rotational and linear speed of equipment such as engines, shafts, and conveyor belts. It requires no batteries and has a large, easy-to-read dial gauge display.
