The PLT200 laser handheld tachometer is a battery-operated multifunctional device designed to measure speed, pulse counting, summation, and time measurements. Thanks to its Class 2M laser sensor, it can accurately measure up to a rotational speed of 200,000 RPM. Pulse detection is done via 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 a quantity of items 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 measurements, 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.
