HTM ATEX Intrinsically Safe Hand-Held Mechanical Tachometer
The HTM ATEX Intrinsically Safe Hand-Held Mechanical 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! 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. 3-Position Range Selector Switch provides highest possible resolution for each application. All HTM-ATEX models are rated at an accuracy of ± 0.5% Full Scale or better.
NIST-Traceable Calibration & Test Report optionally available under p/n NISTCAL Accuracy of 0.5% Full Scale Memory button holds pointer in "last" position until reset NO BATTERIES required 3-Position Range Selector Switch provides highest possible resolution for each application Warranty of 18 months Rubber shell on housing provides extra protection and improved grip Supplied as a complete kit with cone & funnel tip adapters, shaft extension & surface speed wheel in foam-fitted carrying case Over-sized 3" Dial (70mm) uses 2 separate color scales making reading RPM (black) and Surface Speed (red) quick and easy Suitable in all surface industries in hazardous explosive areas
