Notes:

  1. The chemical resistance data of our MTH500HS comes from laboratory environmental testing, and the data is for reference only.
  2. The above table list is the tolerable concentrations of the main gas components. Other chemical components not listed, it do not mean that the sensor will not be corroded by unlisted gas, which will be verified by further expansion experiments.
