TPI 505 Digital Hand Tachometer, 2 x 1.5V Battery

The TPI 505 portable contact/noncontact tachometer measures rotational and surface speed, has a visible light beam and photo diode 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 and surface speed for versatility, and its optical sensor is a visible light beam and photo diode that works at a distance of up to 10 inches for user safety. The five-digit LCD screen presents test results and the unit of measurement, and it can store the maximum, minimum, and last test result values for ease of data recall. The CE mark indicates compliance with applicable EU directives. It comes with a contact adapter, a cone adapter, a funnel adapter, a surface speed test wheel, reflective tape, carrying case, and instructions. This tachometer is suitable for measuring rotational speed and other measurements in mechanical or industrial engineering environments.

Specifications

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

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.
