Drop Counter logger sensor NUL-223

Drop Counter logger sensor


This sensor enables to count automatically drops and bubbles. It is perfect for titrations. Combined with the pH sensor it gives a very nice titration curve.

The sensor comes with a pre calibrated value for the drops volume. The user can make his own calibration.

  • Used in the fields of Chemistry and Biology.
  • Uses an infrared beam which passes between the two endpoints of the sensor probe to count drops. As liquid passes through the infrared beam, infrared light is scattered and not noticed by the infrared detector on the opposing side.
  • Includes a durable plastic drop counter probe attached directly to the sensor’s body by a rubber-coated wire
    and a threaded rod for easy connection to retort stands or other labware.
  • The sensor is pre-calibrated at the factory.
  • Experiment duration: 1 second to 31 days.
