The analyzer is based on a yttria stabilized zirconia cell, that supply the relevant advantages that this measuring principle can guarantee. The absence of cross sensitivity with other gases due to the oxygen vacancy generated in the zirconia substrate is one of the most important feature.

The peculiar drawing of the analysis chamber allows the changing of the flow of the sample without affecting the O2 measure.

The analyzer does not require regular calibrations because it is fully temperature compensated. The measuring principle that does not need any moving parts, ensures a very long life without any service.

The measuring range by volume is very wide O2 values and diagnostic are transmitted with analogical, serial and digital output. Optionally the Hart protocol is available.

This very tough instrument, is ideal to be used in a system for emission monitoring. It cannot be used for measuring O2 in a gas that contains combustibles, because the zirconia cell is warmed up to high temperature.
