Paramagnetic alternating pressure principle

• Small measuring ranges (0 to 0.5% or 99.5 to 100% O₂)

• Absolute linearity

Detector element has no contact with the sample gas

• Applicable in the absence of corrosive sample gases

• Long service life

Physically suppressed zero point possible, e.g. in the measuring range 98% or 99.5% to 100% O₂
