Traceable® Touchless/Contact Dig. Tachometer Complete Description
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. 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. Size is 2-1/2 x 8-1/2 x 1-1/2 and weight is 10-1/2 ounces.
