This instrument is simple to use and offers numerous measurement possibilities with or without contact. Measurement by photo-reflection for no-contact measurement: a reflective strip is positioned on the part to be tested. The optical sensor helps to prevent external disturbances and the active, modulated infrared beam guarantees correct measurements.

For traditional measurement with contact, an optional mechanical adapter (cylinder, cone or calibrated wheel) converts the rotation speed into pulses which are then measured by the tachometer. The CA1727 ensures up to 100,000 RPM using infrared measurement. A combination digital/analog bar graph LCD displays the measurement clearly and accurately. Other features include auto or manual range selection, smoothing, min/max recording and hold functions. Count, alarm and print functions are also provided. An accessory kit of three mechanical adapters for the AEMC CA-1727 allows for direct connection and measurement to rotating shafts and other devices. High and Low alarm levels are programmable as well as display multiplier coefficient "K" (scale factor).

The CA1727 adds PC connectivity to the specification of the CA1725 and is supplied with TachoGraph software
