The Reed R7100 portable contact/noncontact tachometer measures up to 99,999rpm, has a laser beam for noncontact measurements, and a five-digit LCD screen. This contact/noncontact portable tachometer is used for measuring the speed of motors, conveyor belts, and other moving and rotational systems. It measures rotational speed from 10 to 99,999rpm for noncontact measurements, and from 0.5 to 19,999rpm for contact measurements, with + or - 0.05% accuracy. It is autoranging, to display the most appropriate test result value automatically. It measures surface speed from 0.5 to 1,999.9m/min. Its optical sensor is a laser beam that works at a distance from 50 to 500mm for user safety. The LCD screen presents test results and the unit of measurement, and it stores the maximum, minimum, and last test result values for ease of data recall. It comes with a cone contact adapter, a funnel contact adapter, a surface speed wheel, four AA batteries, reflective tape, instructions, and a carrying case. 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.
