Control Company 4059 Touchless/Contact Digital Traceable Tachometer

FEATURES

• Takes only 3 seconds for most readings
• Includes contact readings with a rotating spindle as well as touchless operation

Labs use this high accuracy unit to check speeds of centrifuges, motors, or stirrers. Five digit LCD is a vivid ½-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 of 0.1 to 19,999 revolutions per minute, 0.05 to 1999.9 meters per minute, and 0.2 to 6560 feet per minute. Resolution in all modes is 0.1 below 1000 and 1 above 1000. For accuracy see chart.

Utilizes a precision quartz crystal for an accurate time base.

TRACEABLE® CERTIFICATE

An individually-numbered Traceable® Certificate provided with each unit, assures accuracy from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement.

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.
