Control Company 4059 | Traceable® Touchless/Contact Digital Tachometer, Range: 0 to 99,999 RPM, Dimensions: 2-1/2 x 8-1/2 x 1-1/2in

Traceable® touchless/contact digital tachometer. Labs use this high accuracy unit to check speeds of centrifuges, motors, or stirrers. Five digit LCD is a vivid 1/2-inch high display. Tachometer takes only three seconds for most readings. A unique memory feature permits recalling the highest, lowest, and last reading. Unit is extremely easy to use; operation may be learned in one minute. One end of the unit provides contact readings with a rotating spindle. The other end makes touchless readings using a beam of light. The light may be held as far away as twelve inches. The light beam reflects off self-adhesive tabs to provide readings of 0.1 to 99,999 revolutions per minute (RPM). The contact end of the instrument measures speeds. 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). Comes with four AA Alkaline batteries (for thousands of intermittent readings for over a year), Traceable® Certificate, rugged ABS plastic case, self-adhesive reflecting tabs, internal light, cone for RPM, wheel for RPM, wheel for surface speeds, and carrying case. Replacement battery Cat. No. 1111. Range: 0 to 999.9 RPM; 1000.00 to 99999 RPM. Resolution: 0.1 RPM; 1 RPM. Accuracy: ±0.05% of reading + 0.1 RPM; ±0.05% reading + 1 RPM. Display: 1/2-inch high. Size: 2-1/2 x 8-1/2 x 1-1/2-Inch. Weight: 10-1/2oz. Control Company #: 4059.
