• Lengthy batter life (40-65 hours)
• Minimum shaft loading overspeed protection

The Shimpo DT-105A-S12 portable contact tachometer has a 12-inch wheel, measures rotational speed, linear speed, surface speed, and the total length, and provides 16 different measurement units for rate and speed. This portable contact tachometer has a 12-inch wheel and is used for measuring the speed of motors, conveyor belts, and other moving and rotational systems.

It measures rotational speed, linear speed, surface speed, and total length for flexibility of use, and measures the rate of speed and length in 16 different units for versatility. The five-digit LCD screen presents test results and the unit of measurement. Flashing numerals on the LCD screen indicate speeds outside of the measuring range to help avoid damage to the instrument. It stores up to 13 readings, including the maximum, minimum, and last test result values for ease of data recall.

A die-cast aluminum body provides durability in harsh environments, and the device can be tripod-mounted and locked to take continuous measurements. The tachometer conforms to NIST standards for compliance with regulations, and the CE mark indicates compliance with applicable EU directives. It comes with a 12-inch wheel, two cone adapters, a funnel adapter, a 3.5-inch extension shaft, a carrying case, and a NIST certificate. This tachometer is suitable for measuring rotational speed and other measurements in mechanical or industrial engineering environments.

The Shimpo DT-105A-12 is a battery-operated, handheld, microprocessor-controlled contact type tachometer. It incorporates the latest micro-circuit technology and offers:

• Multi-mode capability - measures RPM, FPM, YPM, mPM, and other units without special accessories
• Large memory capacity
• Wide speed range with an automatic floating decimal point
• C-MOS single chip microprocessor for high reliability and low maintenance
• Rugged construction - die-cast aluminum housing

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 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.
