EXTECH RPM33 Combination Contact/Laser Photo Tachometer

The EXTECH RPM33 Combination Contact/Laser Photo Tachometer is a high-resolution device designed to quickly and accurately measure RPM, total revolutions, frequency, surface speed, and length. Offering enhanced versatility, it provides both contact and non-contact RPM measurements. The contact measurement range spans from 2 to 19,999 RPM, whilst the non-contact photo mode covers 2 to 99,999 RPM.

For added safety and convenience, the laser-guided non-contact measurements can be taken from a distance of up to 1.6 feet (500mm). The device features a large, easy-to-read, 5-digit backlit LCD display, ensuring clear visibility in various lighting conditions. Powered by a microprocessor with a quartz crystal oscillator, it maintains high accuracy of 0.05% with a rapid sampling time of 0.5 seconds.

Data Management and Memory

This tachometer allows users to store and recall up to 10 data sets in memory. Each stored data set includes four parameters: the measurement, maximum, minimum, and average values, providing comprehensive data analysis on the job.

Specifications and Accessories

Built for demanding environments, the tool operates within a temperature range of 0°C to 50°C. It has compact dimensions of 15 mm in depth, 33 mm in width, and 43 mm in height, with a total weight of 361 grams.
