Description

The Ethanol Sensor measures the concentration of gaseous ethanol, from which the concentration of ethanol in a solution may be inferred. The sensor’s probe contains a material whose resistance decreases in the presence of ethanol. The sensor translates this resistance into an ethanol concentration measurement, which is recorded and displayed by the connected computer or datalogger. The Ethanol Sensor is well-suited for continuous recording and discrete measurements.

  • The PASPORT Ethanol Sensor can be used with the EcoChamber (ME-6667) to perform yeast fermentation experiments.  See the full solution.

Other factors that affect measurement

  • The ethanol sensor has a temperature dependent response. See the instruction manual for response curve against temperature.
  • Air flow around or into the probe affects its temperature. Minimize airflow during calibration and measurement.
  • In addition to ethanol gas, the sensor responds to hydrogen, isobutane, carbon monoxide, and methane.

Monitor yeast-based production of ethanol

Monitor yeast activity based on ethanol production at different temperatures, with different concentrations of sugar, or with different types of sugars.
