Tachometer
Provides Precise RPM Readings
with or without Contact
• Incorporates both a photo and contact
tachometer into one instrument.
• Large 0.4", 5-digit LCD Digital Display.
• Measures from 5 to 99,999 RPM in photo mode.
• Simple operations: Turn on, contact rotating
object with sensor tip, allow reading to stabilize
(approx. 2 seconds), and read RPM
with excellent precision.
• Linear surface speed measurements are from
0.2 to 6560 ft/min or 0.05 to 1999.9 m/min.
• Includes an attachable surface wheel
which enables tachometer to read surface
measurements of moving webs or other
linear moving objects.
• Holds last reading for 5 minutes and
recalls min/max readings.
• Autoranging with 0.05% RPM accuracy of
full scale. Achieve 0.1 RPM resolution from
5 to 999.9 RPM and 1 RPM resolution at
higher ranges up to 19999 RPM.
• Complete with cone, RPM sensor tip, surface
speed wheel, 4-1.5 volt AA batteries and carrying case. e.
