I'm redoing some CO2 meters for a client, I have the stationary model and also a portable model, so I'll be measuring some tanks out and about as well as my own.
I also have some controllers and will link them to the mV reading and assume the scale 20mV= 1ppm of CO2 and data log.
I have several methods for calibrating of the CO2 meters I plan on using with known standards.
Not cheap, but lots cheaper than these meters!!
The last test I did was very enlightening.
This time I'll double and triple check things and also calibrate with 3 different methods to ensure what my CO2 really is.
I have two CO2 meters, and new probes, new calibration s kits(Oxyguards, plus 2 of my own methods, one used a KH reference and pH with DI/RO water, another uses Gas at a known concentration of CO2(100ppm and then it'll be cut in 1/2).
