DT-100A Contact Tachometers The Series DT-100A Tachometer with microprocessor technology has heralded a superior standard in tachometer accuracy and capabilities for measuring and recording speeds of rotational, linear and surface plus total length. Offering unprecedented confidence, the DT-100A battery-operated tachometers feature the same rugged, high quality components that have made them the benchmark in the industry. These user-friendly, value-packed units feature memory storage; quick adjustment units knob; length functions; retrieval of last, maximum and minimum values; plus each unit comes standard with a free N.I.S.T. certificate. Units are available with an LCD or vibrant red LED display. Incorporating the precise technology and user-friendly functions as the DT-100A, the DT-100A-S12 provides an exceptional accuracy in measuring speed and length via its 12” wheel. The larger wheel rotates more slowly than a standard 6” wheel, enabling reliable and safe registration of high speeds. Employing a non-slip rubber contact surface, the FPM-12-CBL adds safety and accuracy while measuring speeds on elevator governor cables, wire & cable reels, extruded tubing and many other applications. The FPM-12-KMW, 12” circumference aluminum wheel with knurled edge aids in usage where wheel slippage may occur, and is ideally suited for hot surface temperature applications. Features • Outstanding accuracy allows usage in the strictest applications. • Exceptionally rugged die-cast aluminum housing enables usage in the harshest conditions. • Wide field selection of units in both instantaneous rate as well as totalized length satisfies a multitude of user requirements. • 10 memory capacity allows quick retrieval of stored data plus additional last, max. & min. values. • Long-life battery (25-40 hrs. continuous use) eliminates concerns of being down during testing. • Rear threaded inserts provides option to mount to stand or other device. • Available display options of either LCD or vibrant, bright red LED. • CE Mark combined with free N.I.S.T. certificate affirms instrument quality.
