Measurement in potentially explosive areas - ATEX approved Mechanical Hand-Tachometer

Mindful of the need to operate tachometers in areas where there is sometimes a risk of explosive atmospheres due to either dust particles or gas, our engineers have carried out modifications to enable this version to be certified for use in ATEX zones 1 and 2 without compromising the capability of the original design.

The htm hand-tachometers have been especially 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 hand-tachometers easy to use. With no need for batteries, it has the safety and flexibility to satisfy the most demanding requirements for maintenance and calibration.
