A tachometer is a device that measures the angular speed of a rotating shaft in terms of revolutions per minute (RPM). The Extech 461750 Tachometer features surface wheels that measure contact surface speeds of rotating (10 to 19,999 RPM) and moving (3 to 6,560 ft./minute; 1 to 1999. 9 m/min) objects. Complete with 9V battery and surface wheels.

Perform tachometer RPM measurement, stroboscopic speed and motion analysis with the Extech 461825 Combination Photo Tachometer and Stroboscope. The unique display reverses character direction depending on which measurement mode you are using. The tachometer memory stores last, max, and min readings for recall. The strobe features course and fine flash rate adjustments in 3 ranges. It is complete with 4 AA batteries, reflective tape, and carrying case.

The Extech 461830 is a digital StroboTach tachometer. Freeze motion and analyze rotating objects without contact. Checks and analyzes motion and speed by simply aiming and synchronizing its flash rate (FPM) with a rotating object. Ideal for measuring the speed of moving gears, fans, pumps, motors and other equipment used in general maintenance, production, quality control, or laboratories. Complete with 6 ft power cord, handle and can be tripod mounted.

Uses visible light for non-contact measurements up to 6in. (150mm) from target. Comes with wheels for linear surface speed (0.2 to 6560 ft/m; 0.05 to 1999.9 m/m) or RPM measurements, 4 AA batteries, 23in. (0.6m) reflective tape, and carrying case.

The Extech 461937 is a set of spare Reflective Tape, coming in packs of 10. For use with any non-contact tachometer.

The RPM10 is a combination tachometer which provides both contact and non-contact RPM measurements, making this device useful in virtually all applications. The RPM10 also features a built-in IR thermometer with laser pointer for measuring surface temperature from -4 to 600 degrees F (-20 to 315 degrees C), making it ideal for checking the operating temperature of motors, bearings and machinery. Complete with wheels for linear surface speed (0.2 to 6560 ft. /minute; 0.05 to 1999.9 m/minute) or RPM measurements, 4 AA batteries, 23 in. (0.6 m) reflective tape, carrying case, and user manual.

The Extech RPM250W is a compact Laser Tachometer with Bluetooth connectivity, which allows building and maintenance professionals to view and share revolutions per minute (RPM) data of rotating objects directly from a mobile device using the free ExView app. With the capability to capture data, display trends, set visual and audio alarms, and send reports, users can gain deeper insights on equipment health.
