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

2021-06-12· After the addition phase, the CO2 concentration slowly decreased due to the leakage of the measuring chamber. Here, too, the MH-Zxx sensors reacted more slowly and delivered correspondingly higher values. Here is an example of a result for the MH-Z14 sensor: MH-Z14 vs. Technoline WL 1030. The results for the MH-Z19C looked very similar. Overall ...
