So a variable speed motor can be adjusted manually? man, that sounds like a great option, expect I put a new motor imn like 3 years a ago..but if I have to, I have to. So another question...is the limiting factor on the AQR-15 the cell or the electronics? I dont suppose there is a generic cell that can exceed the 4 ppm output? Needs, how do you calculated the 4ppm? All the comparisons I find always show it as pound or some other measurement..
Thanks again
