Portable digital tachometer with memory, measurement data logger, optical and tactile speed measurement functions, high accuracy, suitable for industrial engines, automobiles and bicycles.--DTEKGAZ

New features of the laser tachometer: Thanks to advanced technologies such as microcontrollers (MCUs), optoelectronics, and semiconductor lasers, it enables non-contact speed measurement. It offers a wide measuring range and high resolution for a smooth transition between manual and automatic modes in various applications. The laser power is adjustable in two stages (high and low) to simplify measurements at short and long distances while protecting the user's eyes from excessive brightness. It can automatically record 50 measurement series with an adjustable sampling interval to meet the measurement requirements of different objects. Maximum, minimum, and average values are recorded during measurement. A backlight facilitates use in dark environments. II.
