The High-Range DO Meter ​​

The high-range dissolved oxygen meter performs a very important quality check on wort heading to the fermenter. Contrary to the goal of low oxygen after fermentation, proper higher levels of oxygen in wort impact yeast health, yeast health, and the final flavor profile.
High-range in this case refers to approximately 0.1-45 ppm, with wort typically falling in the 8-10 ppm range. These high-range instruments are typically optical instruments, measuring a particular wavelength of light given off by oxygen when exposed to another wavelength of light. Suppliers, such as Anton-Parr and Pentair Haffmans, manufacture high-range dissolved oxygen meters geared toward the brewing industry.
