UC09 – Inline Infrared CO-2 analyzer

The carbonation analyzer UC09 is a 100% in line system able to measure accurately CO2 content of any carbonated beverage, beer, wine or mineral water: the installation can be easily made by means of 1 single Varivent fitting with no need of any bypass or pump. The equipment is optical using ATR infrared technology specifically developed by Maselli for this application being able to withstand standard and HT applications. The analyzer does not have any drift in the time so that it does not need any adjustment vs the laboratory: after the initial configuration during start up, the operators in the plant do not have to touch the system anymore. The measurement is very fast (3 seconds) and it helps the plant operators to control the process. Due to the optical technology, no moving parts, the equipment is virtually no maintenance reducing drastically the ownership costs in comparison with the traditional pressure / temperature construction.
