We a CO2 incubator without CO2 indicator. I want to know the traditional ways through which we can know the 5-10% level inside the incubator without CO2 indicators. My second question is this incubator fan is running continuously and there is not any function to close this fan, so, does this mean that the CO2 going inside if expelling outside by this running fan.
The high tech method is IR measurement, and IR monitors are relatively inexpensive. You'd have to calibrate the monitor and plumb it using a pump and gas impermeable tubing. Low tech is not so easy. You need to fill a container of known volume, close it and capture the CO2 inside using something like dilute NaOH or Ba(OH)2 solution and back titrate the excess base.
Does the fan expel air or just circulate it? Paul. .
