You use the testo app to pull in info from the 605is (Bluetooth psychrometer) to read alongside the 550s’ temp & pressure data in the app and calculate capacity.

The 605i Version2 humidity probe tips are a smaller diameter, have integrated magnets and “knee joints*”.

Increasing gas pressure, up to a point, could cause more complete mixing of fuel and air, hence more complete combustion.
