Phasar-Laser Tach Series

NIST

Phasar-Laser combines the accuracy and safety of a non-contact optical tachometer with theconvenience and ease of operation of a pistol grip instrument, housed in a rugged steel enclosure. The tachometer provides a convenient visible red laser for easy targeting along with a latching trigger for hand held operation and a mounting bushing for tripod mounted use. Phasar-Laser-R provides for an optional remote sensor for difficult to reach locations inaddition to the standard internal measurement optics. Features •Convenient pistol grip design•Rugged steel enclosure•Industrial safe non-contact operation to 10 feet (3 m) and 45 degrees from reflective tape•On-target and low battery indicators •Last measurement memory Example Applications: • Engines• Dynamometers• Pumps• Fan blades • Centrifuges• Motors

PORTABLE TACHOMETERS/TOTALIZERS (Non-Contact/Multi-Function) Tach-4A and Tach-4AR Series

NIST

Tach-4A innovated the combination of a high accuracy, wide range Tachometer , multi-function Totalizer/Counter and Timer (Stopwatch) in one versatile instrument. Tach-4A is the world’s mostaccurate portable tachometer, providing resolution of up to 0.0001 RPM. Safe non-contact operation up to 36 inches (91.44cm) and ±45° from perpendicular on a reflective tape target.Tach-4A is menu programmable from a six button membrane keypad. A unique scaling featureallows triggering from one or multiple pulses per revolution as a tachometer, ratemeter and totalizer/counter displaying data in engineering units. Tach-4AR is available with remote sensing capability. Remote sensors may be optical, infrared,magnetic or laser. See Page 7 for optional sensors. The optional 0-5V TTL compatible Pulse Output (PO) is supplied with a cable for BNC interface to data acquisition equipment. Example Applications: • Vibration TTL pulses • Pumps • Trip switches • Fans • Centrifuges • Calibration
