Honeywell MST Sensors NH3 0-100 ppm Version SE 9602-6704
All Honeywell Analytics electrochemical sensor cells are amperometric type i.e. fuel cell type acting like batteries, where one component required to generate a current is missing: The gas to be detected (target gas). The target gas diffuses through a gas permeable membrane into the sensor where an electrochemical reaction results in a low current that is directly proportional to the measured gas concentration (generally a nA/ppm reading).
