Product Description

The Starrett S7793Z portable contact/non-contact tachometer measures rotational speed, linear speed and count. It has a timer, a laser beam for noncontact measurements, and an LCD display screen. This portable tachometer is used for measuring the speed of motors, conveyor belts, and other moving and rotational systems. It can measure rotational speed, linear speed, count, and time for versatility. The tachometer provides contact measurements in in./min, ft./min, yd./min, m/min, or cm/min, and noncontact measurement in rpm for flexibility of use. Its optical sensor is a laser beam that works at a distance of up to 25 feet for user safety. The LCD screen presents test results and the unit of measurement, and it has on-target and low battery indicators. It stores the maximum, minimum, and last test result values for ease of data recall. It is autoranging, to display the most appropriate test result value automatically; or it can be set to display results with a fixed decimal value. This tachometer is suitable for measuring rotational speed and other measurements in mechanical or industrial engineering environments.

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. Contact tachometers are an excellent choice for dirty and dusty environments

Noncontact tachometers take measurements from a distance using a laser light source and provide highly accurate measurements. Non-contact tachometers only calculate rpm but are considered safer because they do not require the operator to be in close contact with the moving surface. 

The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
