Today we want to talk to you again about oxygen and just how important this measurement is, especially TODAY, when we’re in full “CAN MOOD.”
The analysis MUST BE PERFORMED IMMEDIATELY after packaging, because that is when oxygen is present in the solution; however, after just a few hours, the analysis is NO LONGER REPRESENTATIVE because the oxygen is bound by many antioxidant compounds (such as polyphenols), causing a significant drop in the reading.
Presens Pulse Oximeter
Reliable, affordable, and accurate are just a few of the features of our “top pick” pulse oximeter, the OXI-1-SMA—a truly versatile device.
How does the can-based measurement system work?
Thanks to an external attachment—specifically a “piercer” designed for these measurements—we can measure the oxygen content directly from the container, whether it’s a can or a bottle.
Go ahead and poke holes, but don’t do it randomly!
The new piercer is specifically designed so that, during measurement, it is not contaminated by external gases (air) that could significantly affect the reading.
The whole thing works thanks to a sealing gasket that rests against the surface to be drilled; hidden beneath the gasket is a punch shaped like a slice of salami to facilitate penetration.
Before drilling, the gasket must be secured in place, and the entire system must be flushed with CO₂ or, even better, with Nitrogen 5.0 to make the entire circuit anoxic.
Next, we drill a hole and insert the tube (needle) through which the beer will flow until it reaches the measurement cell, which is connected to our oximeter and will provide us with a precise reading of the oxygen level in the flow.
