NIB NEIKO 20713A Digital Tachometer Noncontact Laser Photo Sensor

Description

While a digital speedometer will read the current speed of a vehicle, this automotive tachometer is used for measuring the rpm of a revolving shaft, as with the driveshaft of an automobile.
This handheld tachometer is highly accurate and noncontact. With high-speed laser-aim operation and instant readings from 2.5 to 99,999 rpm, this radar gun gives you accurate rotational speed readings from a distance.
This big- or small-engine tachometer measures velocity in revolutions per minute. The information is displayed on a large and easy-to-read LCD screen.
This pocket radar device is accurate to +/- 0.05% and is capable of measuring at a distance from 2" to 20". It measures revolutions over a 1-second sampling time and stores them as the last, minimum, or maximum reading.
The compact, lightweight design of this photo tachometer makes it easy to get speed readings for diagnostic and measurement purposes. This device operates on 3 AA batteries (included).
