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.
fering 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 userfriendly, 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.
Of-
DT-100A Contact Tachometers
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.
DT-105A
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
DT-107A
• CE Mark combined with free N.I.S.T. certificate affirms instrument quality
