FEATURES:

• Minimum 0.01 r/min resolution and high ± 1 digit precision make the tachometer effective for precise measurements
• By using the optional 9213 contact adapter, the 3403/3404 become contact-type tachometers, while the period ring can be used in applications like measurement of conveyer line speed.
• LED and buzzer signals confirm that the light pulses reflected from the tape on the rotating body are being picked up.
• MIN/MAX mode, TOTAL mode, PERIOD mode, FAST/SLOW sampling mode, and Analog output Multi-function performance for the 3404 only.

• Measurement range r / min:*1 (30.00 to 199.99)range to (20000 to 99990)range, 4 ranges, r / s:*2 (0.5000 to 1.9999)range to (200.0 to 1600.0)range, 4 ranges, *1r / min = rotation per minute, *2r / s = rotation per second
