Extech 461950-NIST Panel Mount Tachometer with 4 digit LED Display, 99990 rpm, 115/230 VAC 50/60Hz, NIST Certificate

The 461950 is a 1/8 DIN Panel Tachometer. Measure rotational motor speed, moving fans, pumps, gears, propeller devices. Choice of 2 sensor pickup types: Proximity sensor-0.1 in. (3 mm) target distance, range up to 36,000rpm (600Hz); Photoelectric sensor-0.4 in. (10 mm) target distance, range up to 6,000rpm (100Hz). 1/8 DIN size. Powered by 115/230VAC 50/60Hz.

Features:

• Measure RPMs from 5 to 99,990rpm with microprocessor quartz crystal accuracy of 0.05% + 1digit
• Resolution from 0.1rpm (5 to 1000rpm) to 1rpm (1000 to 9999rpm) to 10rpm (10,000rpm to 99,990rpm)
• Large 4 digit LED display updates once per second (rpm greater than 60)
• 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
