- Precision quartz crystal for an accurate time base
- Touchless, no contact
- Five digit LCD
Touchless, no contact operation is safe and easy. Tachometer measures revolutions per minute anywhere from two to twelve inches away from any rotating object. Labs and plants use this high accuracy unit to read speeds of centrifuges, motors and stirrers.
Five digits LCD is a highly visible 0.5" display. Unit shines a beam of light, which reflects off of self-adhesive tabs to give readings of 0.1 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. A certificate is provided to indicate traceability to standards by NIST.
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 case, self-adhesive reflecting tabs, internal light, and carrying case. Size is 2-3/4 x 7-1/2 x 1-1/2" (7/19.1 x 3.8 cm) and weight is 9 ounces (255 grams).
