例如Checkline HTM型是一款防爆型機(jī)械手持式轉(zhuǎn)速計(jì)，測(cè)量轉(zhuǎn)速和表面速度。適用于電梯維修和采礦業(yè)。
The new CHECK-LINE HTM explosion proof tachometer is certified EEx ia IIC T4 - ATEX II 2 G to allow for use in a wide range of hazardous environments including petrochemical, Gas & volatile materials processing industries.
4 Models, 2-English & 2-Metric
Checkline HTM-100F 10-10,000 rpm/5-5,000 ft/min
Check-Line HTM-500F 30-50,000 rpm/15-25,000 ft/min
Check-Line HTM-100M 10-10,000 rpm/1-1,000 m/min

The new HTM 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!
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 models are rated at an accuracy of ± 0.5% Full Scale or better.
The HTM is supplied fitted with a durable rubber sleeve providing extra ergonomic benefits for comfortable and secure hand-held use and provided 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 10X for reading of dial.
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
