The AEMC CA1725 / CA1727 tachometers can measure the rotation speed of any moving part or device. A photo reflective strip facilitates distance measurements. The optical sensor avoids external interference by incorporating an active, modulated infrared beam ensuring measurement accuracy.°

The CA1725 and CA1727 models both include an adapter for traditional contact type measurement. Additionally, these instruments can measure from sensors with voltage outputs through an external input. These tachometers feature extensive programming possibilities with multiple functions and automatic routines for data acquisition and storage including the measurement of rotational speed, linear speed, count, frequency and period functions.

The Model CA1727 includes a USB connection and software specific to tachometers, which facilitates recording and data analysis. The LCD display includes both a digital readout and a 42-segment bar graph. Other functions include Min, Max, Hold and Alarms.
