Hand-Held Tachometers

HTM-ATEX


The new HTM-ATEX intrinsically safe mechanical hand-tachometer is designed to accurately measure RPM and surface speed on a wide range of applications. Favored in several industries, including elevator maintenance, mining industry, and others, Mechanical Tachometers using a pointer and dial to display RPM or surface speed — without the need for batteries!

Models Available
HTM-100F-ATEX
ATEX-Certified Hand-Held Mechanical Tach, complete Kit (10-10,000 rpm/5-5,000 ft/min) w/ 6″ circumference surface speed wheel – A3-5110
