WSF-2000MH Fermograph III

AF-1101 Fermograph II-W

Purpose and Application

  • Automatically measure gas production for up to 20 samples
  • Evaluating fermentation capacity of microorganism or yeast
  • Evaluating culture medium/material composition and fermentation conditions
  • Used for breeding, development, and quality control etc.


  • Simultaneous measurement of gas production up to 20 samples
  • Measure total gas generation, gas production per hour (gas increase, gas production rate), gas quantity produced in the dough, etc.
  • In addition to bread dough, it can also continuously measure for more than a few days such as sake, yeast culture solution, bioethanol production medium, etc.
  • Measure samples that produce gas in a short period of time, like baking powder.
  • Data correction by environmental temperature with temperature sensor in device
