Many vendors of ventilation controllers have two ventilation rate settings: the rate for when the CO2 level is below 1000PPM and the rate for when the CO2 level is above 1000PPM.

WebMar 9, 2024 · So this is basically “parts per part,” meaning that for one part solution you have 0.0002 parts salt. But of course, having this many decimal points isn’t exactly convenient, so to convert to PPM you multiply by 1,000,000 = 10 6, giving: 0.0002 × 10 6 = 220 PPM.
