The innovative TACH-4A is the first portable optical instrument to combine a high accuracy wide range Tachometer, multi-function Totalizer/Counter and a Timer (Stopwatch). The TACH-4A has powerful internal optics. TACH-4AR has internal optics and can be used with a Remote Optical Sensor, Infrared Sensor, and Laser Sensor. TACH-4A is menu programmable from a 6 push-button membrane keypad

The instrument's unique scaling capability allows it to be used with one or multiple pulses per resolution as a Tachometer, Ratemeter, and Totalizer/Counter displaying data in real engineering units. A 0-5V TTL compatible Pulse Output is available. The novel TACH-4A and TACH-4AR are highly accurate rugged instruments designed for field and laboratory applications.
