changes the rules Electrochemical cells deplete meaning they have to be regularly replaced.
does not use depleting technology so it doesn't
need to be exchanged.
doesn't need to changed or serviced, therefore
the lifetime cost compares favourably with electrochemical cells
Electrochemical cells will usually be calibrated daily, but because it uses paramagnetic technology,
will typically only need calibrating once a
week
uses a diffusion principle, so it requires
the same gas sampling system as an electrochemical cell.
