|
The new patented design of the EXTECH 461895, Combination Contact / Photo Tachometer incorporates both a photo and contact tachometer into one precision instrument. Characters on large digit display reverse direction depending on which measurement mode you are in. Accurate to 0.05
Microprocessor precision permits reading to a resolution of 0.1 RPM in either photo or contact mode
Wide ranges from 0.5 to 20,000 RPM in a contact mode 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 0.05 to 1999.9 m/min.
Memory / Min / Max buttons holds last reading for 5 minutes recalls min/max readings
