The Amprobe TACH20 hand-held tachometer accurately measures rotational or surface speed as well as length. It comes with a large LCD display that allows the user to easily read the measurement. It also has a built in memory function that permits automatic storage of maximum, minimum, average values plus the last measurement displayed.The TACH20 is supplied with all the necessary accessories designed with optimal mechanical stability to ensure accurate, reliable, and repeatable measurements. In addition to the mechanical adaptor that accepts a variety of tips, as well as the surface speed wheel for contact rpm measurement, the TACH20 can perform non-contact measurement by using the infrared beam function.

The ATP DT-6236B is a optical/contact tachometer for measuring speeds of rotating objects in RPM or for measuring surface speeds in meters per minute or feet per minute. The high accuracy of the APT DT-6236B is achieved by combining CPU, photoelectrical and laser techniques. The ergonomic design of the APT DT-6236B makes the instrument comfortable to use.

The Extech RPM33 combination contact/laser photo tachometer allows you to quickly measure RPM, surface speed and length with one tool. Use the contact wheel for up-close readings or laser mode for safer, non-contact measurements up to 500mm (1.6ft) away. Contact RPM applications include measurments on flywheels, conveyors, pumps and lifts. Non-Contact RPM applications include measurements on motors, fans and gears. The tachometer is microprocessor based with a quartz crystal oscillator to maintain high accuracy and with enough memory to store and recall 10 data sets with 4 parameters (measurement, max., min. and average). Because it has two measurement methods it is able to provide a wide range of RPM (photo and contact) and linear surface speed/length (contact) measurements. Supplied complete with a contact wheel for rpm or linear surface speed/length, 1 x 9V battery, reflective tape and a soft case.

• Large 5 digit backlit LCD display
• Make non-contact laser distance measurements from up to 500mm (1.6ft) away
• RPM range 2 to 99,999 (photo), 2 to 20,000 (contact)
• Dimensions 160 x 60 x 42mm (6.2 x 2.3 x 1.6in)
• Weight 151g (5.3oz)

This pocket-sized tachometer from Testo provides you with quick and reliable readings when carrying out checks on fans, crankshafts and motors. And because the checks can be performed while the machines are still running, there is no need to stop production or shut down machinery.

The Voltcraft DT-30LK is a 2 to 200000rpm Tachometer that has been designed to measure and display rotation speed and belt speed. The given measurements are either non-contact via the built-in laser or per direct contact using the included adaptors.

The rotation speed can be displayed in RPM (revolutions per minute), Hz, m/min, in/min, ft/min and yd/min. The product can also display the total number of revolutions during measurement. The distance of belts can be shown in m, in, ft and yd.

The measured values are shown on the 5-digit LCD display. The product features a memory with space for 40 measured values which allows the user to retrieve the maximum, minimum and average values from a stored measuring procedure. The power is supplied from a 9V block battery (supplied).
