My name is Kevin Curran. For my science project I need to know if there is
anyway to measure carbon dioxide inside a small greenhouse.
You can measure carbon dioxide with a Fyrite device. This is a registered
trademark I think. Heating and air conditioner people use them. I use one in my
laboratatory to measure CO2 in an incubator I use to grow cells. It is simple to use.
Maybe a heating contractor will let you borrow one or maybe you can by one. Never
use one without reading and understanding the instructions. Never use it for the
first time without adult supervision as t it can be dangerous if used incorrectly.
