The HTM-ATEX mechanical hand-tachometer is designed to accurately measure RPM and surface speed on a wide range of applications.
This tachometer is using a pointer and dial to display RPM or surface speed.

Additionally, the range of variation and frequency of variation of the measurement is evident with the speed and span of the movement of the pointer. Includes Peak-Hold button. The 3-Position Range Selector Switch provides the highest possible resolution for each application.

The HTM is supplied with a durable rubber sleeve providing extra ergonomic benefits for comfortable and secure hand-held use and provides an additional measure of physical & environmental protection.
The RED 3-Position Range Selector Switch provides highest possible resolution for each application providing a multiplier of 1X, 10X or 100X for reading of dial.

This ATEX approved version is suitable for zone 1 use, in all gas groups with a temperature class of T4 and is also suitable for mining applications I M2 c.
