Precise rotation speed meter

• MIN/MAX mode, TOTAL mode, PERIOD mode, FAST/SLOW sampling mode, and Analog output.
• 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 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
