TA500 Series Digital Tachometer Measure rotational speed, surface speed, and distance with the TA500 series digital tachometer. Ideal for industries such as electric power, steel, petrochemical, aviation, fan manufacturing, pipeline ventilation systems, and underground storage. Features: Accurate RPM Meter: This handheld, highly accurate, non-contact tachometer offers a wide measuring range from 3RPM to 100,000 RPM with high resolution, providing precise rotational speed readings from a distance. Contact & Non-contact Tachometer: Our digital tachometer supports both contact and photoelectric laser non-contact methods, allowing photoelectric speed measurement, light source flicker frequency measurement, contact RPM measurement, and contact line speed measurement. Wide Speed Range: The digital non-contact tachometer displays rotation speeds from 3-100,000 RPM, while contact type tachometers can measure 3-19,999 RPM, 0-99,999m, 0-1999.9m/min, and 0-9999.9ft/min. Multi-Functionality: This tachometer records maximum and minimum values and includes features such as data hold and automatic shutdown. HD Backlit Display: Equipped with a high-definition LCD backlit display for easy reading in low-light conditions. Wide Application: Suitable for use in manufacturing industries like motors, fans, paper, plastic, chemical fiber, washing machines, automobiles, aircraft, and ships.
