For greater adaptability, the Extech RPM33 measures revolutions per minute using both contact (2 to 19,999 rpm) and non-contact (2 to 99,999 rpm). Safely record laser-guided non-contact RPM measurements from up to 500 mm (1.6 feet) away. The RPM33 is displayed on a big five-digit backlit LCD. Memorize and recall ten data sets with four parameters (measurement, maximum, minimum, and average). The unit includes a contact wheel for measuring linear surface speed (0 to 1999.9 meters per minute; 0.2 to 6560 feet per minute) or RPM, a 9-volt battery, reflective tape, a carrying case, and a user manual.

The Extech RPM250W is a small laser tachometer with Bluetooth® connectivity that enables building and maintenance workers to see and share revolutions per minute (RPM) data of rotating objects directly from a mobile device via the free ExView® app. Users can receive deeper insights into the health of their equipment by capturing data, displaying trends, setting visual and auditory alarms, and sending reports.
Photo/Contact Tachometer with built-in InfraRed Thermometer
The RPM10 is a combined tachometer that can measure both contact and non-contact RPM, making it suitable for a wide range of applications. The RPM10 also has an infrared thermometer with a laser pointer for measuring surface temperature from -4 to 600 degrees Fahrenheit (-20 to 315 degrees Celsius), making it perfect for monitoring the operating temperature of motors, bearings, and machinery. Complete with wheels for linear surface speed (0.2 to 6560 ft/min; 0.05 to 1999.9 m/min) or RPM measurements, 4 AA batteries, and a 23-inch length. (0.6 m) of reflective tape, carrying box, and usage instructions.
The Extech 461995 Combination Contact/Laser Photo Tachometer offers both contact (0. 5 RPM to 19,999 RPM) and non-contact (10 RPM to 99,999 RPM) RPM measurement features for use in almost any application. Laser-guided non-contact measuring up to 2 m (6.5 ft) distant for improved safety and convenience. The kit includes wheels for measuring linear surface speed or RPM, 4 AA batteries, 0.6 m (23 in) of reflective tape, a carrying bag, and a user handbook.
