[Stoves] CO monitoring seeking practical analogues in localtesting methods for the 90% of the rest of us

[Anand Karve]

Dear Richard,
When CO combines with haemoglobin, the CO-haemoglobin complex has a
different colour than normal haemoglobin. I am quite sure that there are
other chemicals too that bind with CO and I feel that it is quite posible to
devise a paper strip that turns its colour when exposed to CO.
Yours
A.D.Karve
