Mechanical hand-tachometers

The mechanical hand-Tachometers htm are designed to accurately measure RPM and surface speed on a wide range of applications. The htm is a favored measurement device in several industries, including elevator maintenance, mining industry and others. The large, clear and easy-to-read dial as well as the wide reading range with good definition make the mechanical hand-tachometers easy to use - without the need for batteries!

The memory button retains last recording until reset. The red 3-position range selector switch provides highest possible resolution for each application providing a multiplier of 1x, 10x or 100x of measured value display. All htm models are rated at an accuracy of ± 0.5% full scale or better. 

This device is also available from RHEINTACHO UK in an ATEX version.
