SKU: RPM33-NIST
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.

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.
The 461891 is a contact Tachometer. Surface wheels measure contact surface speeds (10 to 9,999 rpm) of rotating objects. The memory button holds last reading and recalls min/max readings display. Complete with wheels for linear surface speed (0.2 to 6560 feet/minute; 0.05 to 1999.9 meters/minute) or RPM measurements. Comes with cone tip, flat tip and spare wheel for surface speed measurements, four AA batteries, carrying case, and user manual.
