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 9,999 RPM) and moving (3 to 6,560 ft./minute; 1 to 1999. 9 m/min) objects. Complete with 9V battery and surface wheels.

The Extech RPM33 provides both contact (2 to 19,999 rpm) and non-contact (2 to 99,999 rpm) revolutions per minute measurements for enhanced versatility. Safely record laser-guided non contact RPM measurements from up to 500 mm (1.6 feet) away. The RPM33 displays on the large five-digit backlit LCD. Store and recall 10 data sets in memory with four parameters (measurement, max, min and average). The unit comes with contact wheel for linear surface speed 0 to 1999.9 meters/minute; 0.2 to 6560 feet/minute) or RPM measurements, 9-volt battery, 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.
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.
