Description
Touchless, no contact operation is safe and easy. Tachometer measures revolutions per minute with laser pin-point accuracy anywhere from two to seventy-eight inches away from any rotating object. Labs and plants use this high accuracy unit to read speeds of centrifuges, motors, and stirrers.Five digit LCD is a highly visible 3/8-inch-high display. Laser beam reflects off self-adhesive tabs to give readings of 10 to 99,999 revolutions per minute. Resolution is 0.1 below 1000 and 1 above. Accuracy is ±1 RPM or 0.05%.Utilizes a precision quartz crystal for an accurate time base. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Takes only a second for most readings. A memory feature permits recalling the last reading at any time.Supplied with Traceable® Certificate, four AA alkaline batteries, rugged ABS plastic case, self-adhesive reflecting tabs, internal light, and carrying case. Size is 3 x 8-1/4 x 1-1/2 inches and weight is 9-3/4 ounces.
