The Shimpo DT-107A portable contact tachometer has a six-inch wheel, measures rotational speed, linear speed, surface speed, and total length, and provides 16 different measurement units for rate and speed. This portable contact tachometer has a six-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 LED screen presents test results and the unit of measurement. Flashing numerals on the LED 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 six-inch wheel, two cone adapters, a funnel adapter, a 3.5-inch extension shaft, a carrying case, and an NIST certificate. This tachometer is suitable for measuring rotational speed and other measurements in mechanical or industrial engineering environments.

Tachometers measure the rate of rotation or surface speed of motors, conveyor belts, and other moving systems. Contact tachometers take measurements through direct contact with the moving surface, and can measure both rpm and surface speed. Typically, contact tachometers come with a range of attachments that can be used to measure speed on different kinds of rotary systems, which may include tips used for measuring shafts with a central hole or flat end surfaces, and rotary wheels for measuring conveyor belts. Noncontact tachometers take measurements from a distance using a beam of infrared light, and provide highly accurate measurements. Contact tachometers are an excellent choice for dirty and dusty environments; noncontact tachometers only calculate rpm but are considered safer because they do not require the operator to be in close contact with the moving surface. Contact/noncontact tachometers, also known as dual, or combination tachometers, can be used to take contact and noncontact measurements. Some tachometers can also take other types of measurements, such as count or frequency, while others can output data to a computer for analysis. Tachometers are used in applications such as automobile maintenance, mechanical engineering, and maintenance of industrial equipment.
