- PT-106-N is below 15 psig (pressures above ~17.08 psig are not going to be read so we are blind above this value. Discussions about increasing the readout range will be done after the holidaysshield relieves at 35 psi, pay attention to not exceed that value).
- PT-110-N reads a value between 20psig-65psig.
