The Extech 461750-NIST Tachometer is a reliable and versatile instrument designed for measuring contact surface speeds of rotating and moving objects. This tachometer is an essential tool for applications that require accurate speed measurements.

The Extech 461750 features surface wheels that allow you to measure contact surface speeds of rotating objects within a range of 10 to 9,999 RPM (revolutions per minute). This enables you to obtain precise readings of the rotational speed of various machinery and equipment.

In addition, the tachometer can also measure the contact surface speed of moving objects within a range of 3 to 6,560 feet per minute (ft./minute) or 1 to 1999.9 meters per minute (m/min). This feature is useful for measuring the speed of conveyor belts, moving vehicles, and other objects in motion.

The Extech 461750 provides reliable and accurate measurements to help you assess the speed of rotating and moving objects. Its user-friendly design allows for easy operation and quick access to the measured data.

With its compact size and lightweight construction, the Extech 461750 is portable and convenient to use in various environments. It is an ideal tool for maintenance technicians, equipment operators, and anyone who needs to measure rotational or linear speeds accurately. It includes NIST Certification.
