The “CanNeed-L-100 CO2 Purity Tester” adopts Alkali Absorption Method to measure the purity of CO2. It is widely used in gas monitoring station and brewery plants. CanNeed-L-100 is a CO2 purity tester with the highest accuracy of the world. Accuracy: 0.001%.
When insert CO2 into the beer, please try to not to contain O2 in the added CO2. Otherwise, a mount of CO2 inserted into the beer at high pressure will lead to increasing the dissolved O2 rapidly. Using L-100 with high accuracy of 0.001% to monitor the purity of adding CO2 can effectively evaluate the effects CO2 has on the dissolved O2 in beer. When inserting CO2 in high pressure, the dissolved O2 in the CO2 has the following effects on the O2 of beer:
The inserting CO2 The O2 in CO2 (%)
0.001% 0.005% 0.02%
1 g/liter 7 ppb 35 ppb 142 ppb
2 g/liter 14 ppb 71 ppb 284 ppb
4 g/liter 28 ppb 142 ppb 567ppb
The adding dissolved O2 in beer (ppb)
