“We have one unit in a room where liquid nitrogen is stored. It is generally confirming our calculations that it would take a disaster to dump enough nitrogen into this room to be harmful. Once when a fairly lengthy venting and filling operation was carried out it briefly alarmed at the 19.5% level.

Of course we have enjoyed playing with it and sticking the sample port in a beaker of nitrogen gas.

We are very happy to have this unit. We have instructed all lab personnel not to enter the room during an alarm and it may indeed protect us in that unlikely disaster.
