Series DT-107A (LED) Contact Tachometers
The Series DT-107A 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-107A 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-107A, the DT-107A-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.
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
- Large 5 digit display aids user visibility
- Expansive 10 measurement 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
- Compact, ergonomic design allows easy grip
- 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 provides peace of mind due to the quality of the instrument
