How Does It Work?  The next time you see a beer commercial or drink a cold draft, take the time to appreciate the importance of carbon dioxide in the brewing process. In The Beginning Beer starts out as wort, a mix of water and natural grains. When Brewer’s yeast (a fungi) is added to the mix, it "eats" the starches and sugars in the wort while giving off alcohol and carbon dioxide (CO2) gas. It is the infinitely variable combinations of water, grains, yeast, alcohol levels and the amount of carbonation which give each beer its unique color and taste. Fermentation During fermentation, the CO2 given...

In this article, we outline 5 reasons why you may consider turning off the CO2 supply at night via your CO2 monitor and controller.

If you cannot communicate between your sensor module or CO2 meter and the GasLab® Software on your computer, the problem may be caused by Windows not recognizing the correct drivers needed to create a chain from USB -> FTDI -> UART in order to communicate with the device. The drivers create a virtual COM port. If the device is plugged in before GasLab is installed, the correct drivers will not be found, even if GasLab is installed later. The solution is to uninstall the old (usually incorrect) drivers manually, install GasLab if it is not already installed, then plug your...

Composting is a common method for organic waste disposal. In composting, micro-organisms convert waste into useful products like fertilizer. There are 2 kinds of composting: aerobic (with air) and anaerobic (without air). Although both break down organic matter, aerobic composting depends on micro-organisms that get oxygen from the air, whereas anaerobic composting depends on micro-organisms that get oxygen directly from the waste matter. Aerobic Composting The advantages of composting is that it naturally kills pathogens like E. coli, converts ammonia nitrogen to organic nitrogen and reduces the waste volume. The disadvantages of composting are the loss of some nutrients including...

If you work with gases like we do at CO2Meter, you already know that the ideal gas law PV=nRT shows that absolute gas concentration decreases as temperature increases. This relationship is important to anyone measuring oxygen levels during combustion, fermentation, distillation or algae production. But like they say, “a picture is worth a thousand words.” That’s what we discovered when we measured the change in oxygen gas levels in a sealed environment using our UVFlux 25% Oxygen sensor and Gaslab software. Using the built-in RS232 protocol, the UVFlux sensor samples both the oxygen level and the temperature inside the sensor...
