Possible replacement gas filling
https://groups.io/g/TekScopes/topic/30956868:
HFC236-FA has almost precisely the same characteristics as R114 (boiling point and vapour pressure), is environmentally friendly, and is used both as a refrigerant (a R114 replacement) and in fire extinguishers. So it should be a perfect solution to keeping the P6015 up and running.
R144 has a permittivity/dielectric constant of ≈2 as a liquid and near 1 as a gas.
