RE:RE:RE:RE:RE:Replacement Chamber CostOk, I give up. I am giving out society more credit that alarms would not be going off every day or multiple times a day. And if they do, it will cost a school $600 and the school shouldbbe shut down gor 14 days, if we want to be serious about it. If not, then we can save millions as a society on avoiding equipment purchases and will keep spending 100s of billions instead like we have been doing. There will be businesses that will see the benefit outweigh the cost of cartridges. Those are our clients. We need to sell a few thousand units every year to do well.
