One meter provides precise RPM measurements with or
New patented design. Incorporates both a photo and
contact tachometer into one precision instrument. Characters on the
large 5 digit display reverse direction depending on which measurement
mode you are in. Accurate to 0.08%.
Microprocessor precision. Permits readings to a resolution
of 0.1 RPM in either photo or contact mode.
Wider ranges. From 0.5 to 20,000 RPM in contact mode
and from 0.5 to 99,999 RPM in photo mode. Linear surface speed measurements
are also increased to 0.2 to 6560 Ft/min. or 0.5 to 1999.9M/sec.
Memory/Min/Max button. Holds last readings for 5 minutes
and recalls min/max readings.
Complete with accessoiries : wheels for linear surface
speed or RPM measurements, four 1.5 Volt AA batteries, reflective tape.
