DROP AND BUBBLE COUNTER

$170.00

This sensor offers exceptional value as it performs a dual role. In Chemistry its primary role is as a drop counter measuring accurately the volume of titrant added during a titration. However, this sensor can be used to monitor bubbles produced during gas production from either a chemical reaction or a biological process.

When operating as a drop counter, titrant is uniformly dripped from the supplied reservoir and optically recorded. If desired, the drops can be automatically converted to a volume measurement by following a simple calibration procedure.

As a bubble counter, the sensor counts optically the number of bubbles, from either a chemical or biological source, ascending through the plastic tubing. This method is unique in that it accurately measure the range of gas production and is ideal for biological investigations.

Chemistry:

  • Acid-base Titrations with pH
  • Conductometric titrations with Conductivity sensor
  • Gas production – rates of reaction e.g. marble chips and acid.

Biology:

  • Fermentation
  • Yeast activity

Drop and Bubble Count range of 0 – 10,000 – this range counts the absolute number of drops or bubbles detected as they pass through the sensor’s light beam.

Data is displayed as the total number of drops or bubbles.

Note: Small fine bubbles such as those produced by oxygenating pond weed are unlikely to be detected.

Calibrated Volume ranges:

  • 23 drops/cm3
  • 25 drops/ cm3
  • 26 drops/ cm3
  • 27 drops/cm3
  • 28 drops/ cm3
  • 29 drops/ cm3

The drop count is automatically converted and displayed as volume from 0 – 120 cm3.

Works with the following Dataloggers:

VHub4 and VHub8
