Carbon dioxide (CO2) is colorless and odorless, so you can’t detect it through direct observation. The most effective way to test for CO2 is to bubble the gas through “limewater”, a diluted solution of calcium hydroxide (slaked lime). When you bubble carbon dioxide through the solution, it forms a solid precipitate of calcium carbonate – chalk or limestone. Calcium carbonate is insoluble in water.
If you find the above test troublesome, you might as well take a look at the carbon dioxide leak detector.
The CO2 carbon dioxide leak detector is used in a variety of applications and industries such as Beverage, Wineries, Breweries and many others. … The SR-909-CO2-B carbon dioxide leak detector features an advanced, NDIR sensor technology providing accurate, reliable, and highly sensitive tracking of even the smallest CO2 leaks.
