If the “CanNeed-IAM-30 Air Meter” is used together with CanNeed-CAN-7001 CO2 Tester and Pressure Tester, it can test CO2 content as well as the air content.
It is designed according to ASBC Theory of American Society of Brewing Chemists, corresponding to “GB/T 4928 – 2001 Brewing Analysis Methods” and “GB/T 10792 – 1995 Carbonated Beverage Analysis Methods”. Therefore, the machine is widely used by Quality and Technical Supervision Bureau and beverage enterprises.
After piercing the bottles or cans with the CO2 Tester, the gas in the bottled beer or canned beer will enter IAM-30, touch the alkaline liquid, then CO2 will be absorbed by alkaline liquid. The remaining gas (usually, N2 and O2) will concentrate to the top of measuring tube. The gas volume will be read through the graduation of measuring tube.
