The Shimpo™ DT-105A-S12 is a battery-operated, handheld, microprocessor-controlled contact type tachometer with a 12" wheel. It measures rotational speed, linear speed, surface speed, and total length and provides 16 different measurement units for rate and speed 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.
