MH-Z14 and MH-Z19 CO2 Sensors • Wolles Elektronikkiste

2021-06-12· MH-Z14 vs. Technoline WL 1030. The results for the MH-Z19C looked very similar. Overall, I was as surprised as I was pleased with the good measurement results. However, it is also important here that the zero point calibration (more precisely the 400 ppm calibration) is carried out carefully. And this happens with poor calibration . If you perform the calibration in a not thoroughly aired ...
