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 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 of self-adhesive tabs to provide readings of 0.1 to 99,999
revolutions per minute.
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. Accuracy is ±1 digit or 0.5%. 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.
