The PLT200 laser handheld tachometer is a battery-operated multifunctional device designed to measure speed, pulse counting, summation, and time measurements. With its Class 2M laser sensor, it can accurately measure up to a rotational speed of 200,000 RPM. Pulse detection is carried out using a corresponding reflective tape. An internal memory allows for the recording of the maximum and minimum values of the rotational speed. The summation function can be used, for example, to measure the number of pieces or the number of revolutions of a shaft. An input socket enables triggering and pulse detection via an external sensor with a TTL signal. For contact measurement, there is an adapter with standard measuring tips. Through an output socket, the detected pulses can be transmitted 1:1 to, for example, an additional display.
