The Extech 461950 1/8 DIN Panel Tachometer measures 5 to 99,990 rpm using optional Proximity or Photoelectric sensors. The instrument has microprocessor quartz crystal accuracy of 0.05% + 1 digit, resolution from 0.1 rpm (5 to 1000 rpm) to 1 rpm (1000 to 9999 rpm) to 10 rpm (10,000 to 99,990 rpm). The large 4 digit LED display updates once per second (rpm greater than 60). A unique design permits RPM measurements of a one hole gear or disk eliminating the need for special gears. A pulse is measured when a ferrous object (stud) passes by sensor. The instrument is powered by 115/230 VAC 50/60Hz.
The Extech 461950 is a continuous and accurate panel mount tachometer designed for industrial and engineering applications. It measures RPM from 5 to 99,990 using microprocessor quartz crystal technology with an accuracy of 0.05% + 1 digit.
