result in measured value drift and temperature-related measuring errors.
● The sample gas/reference gas must be free from dust and condensation. The dust filter
● Connect the corresponding absorption filter before the device to filter out components
● Make sure that the sample gas does not condense in the gas preparation unit and in the
