With the Testo 465 (0563 0465) Non-Contact RPM Tachometer, you can measure rpm easily without contact and while using only one hand. The measuring instrument is therefore suitable for measurements on rotating parts such as ventilators and shafts. Simply attach a reflective marker (optional, available separately) to the measurement object, point the visible red beam of light at the reflective marker, and measure. The distance to the measurement object is up to 600 mm. The measuring instrument stores mean, min. and max. values as well as the last measurement value. The SoftCase included in delivery protects the instrument from impact, ensuring an especially long working life.
