* The XZR200 is designed to be operated at atmospheric pressures. However, it is possible to
measure in the range 0 to 25% O

at pressures up to 3 barg (43.5 psig) without damage to the unit.
The unit will require calibration at the operating pressure and a separate pressure transducer feeding
into the control system may be required.
