KROST techo1 Digital Laser Non-Contact Photo Tachometer Rpm Measurer

This high quality non-contact tachometer has wide measuring range and high resolution. With led or laser, it precisely measure rotational speed (rpm)without touching the rotating or moving object. Offering high ±0. 05% Accuracy, instantaneous response time, auto-select test range, low power consumption giving a longer battery life and long detecting distance of up to 500mm or 20 inches (with laser). Operation is very simple, just apply a reflective mark (included in package) onto the target object, then aim the beam at the mark and rpm will be seen on its 5-digit clear lcd. Wide range of applications include measuring rotating speed of machine, motors, model cars, automotive, trucks, aircraft, light rail vehicles, wheels, lathe for metal or wood cutting work, for hvac applications to measure fan speed and other application that needed rotational speed measurements. Features tested according to european international guidelines and standards (ce marking) wide measuring range of 2. 5~99, 999Rpm high accuracy up to ±0. 05% High resolution long detecting distance up to 500mm(20 inch) with laser large 5 digits lcd display auto test range select use microcomputer lsi circuit and crystal time base offering high accuracy and quick measurement time highly accurate, displays exact rpm with no guessing errors with fraction of minute sampling time(0. 8 Sec) maximum, minimum and last measured value low battery indication durable and reliable.
