RheinTacho EchoTach Digital Optical Tachometer
Compact, Reliable Non-Contact RPM Measurement
The RheinTacho EchoTach is a robust, handheld optical tachometer designed for the fast and accurate measurement of rotational speed without requiring physical contact with the target. Its compact, lightweight, pocket-sized design makes it ideal for maintenance professionals, field service technicians, and workshop environments where portability and convenience are essential.
Using advanced optical sensing technology, the EchoTach measures speeds from 1 to 60,000 RPM with exceptional accuracy. A high-intensity red LED projects a beam onto a reflective target attached to the rotating component, while the reflected signal is detected and processed to provide instant speed measurements.
Designed for ease of use, the EchoTach can perform measurements from distances of up to 450 mm and over a wide measuring angle, allowing users to safely evaluate rotating machinery without interrupting operation. Its matched optical system and powerful LED technology provide excellent resistance to ambient light interference, ensuring reliable readings in a variety of industrial environments.
Manufactured in Germany, the EchoTach combines precision engineering, rugged construction, and dependable performance, making it suitable for routine maintenance, machine commissioning, process monitoring, quality control, and laboratory applications.
