This general purpose tool permits non-contact rational measurements between 5 and 100,000 rpm. The optional contact tip allows contact measurements of 5 to 20,000 rpm and linear speed measurements of 5 to 20,000 in/min.
The device can function both as a tachometer and a count totalizer. This meter stores min, max and last measurement in memory and is programmable to read in English or Metric units. Accuracy for each is +/- 0.01% of reading in non-contact mode and +/- 0.5% of reading in contact mode.
