Stable support thanks to CITREX Stand.

CITREX Stand provides additional stability for testing on smooth surfaces. The mobile pedestal is equipped with two magnets to connect it to the gas flow and pressure analysers CITREX H3, CITREX H4 and CITREX H5. The mounting angle is steplessly adjustable. The CITREX H3, CITREX H4 and CITREX H5 transport bag provides enough space to carry CITREX Stand, which can be folded for transport and storage.


Oxygen Sensor

Oxygen measurement with highest precision.

The fast and accurate measurement of the oxygen concentration is an important criterion for the verification and calibration of respiratory and anaesthesia devices. The oxygen sensor was specially designed for our CITREX devices to offer long-lasting and reliable functionality.

However, a precise oxygen sensor alone is not sufficient for accurate measurement results. This is why all of our analysers have fully automated and self-contained calibration functions for oxygen sensors. This ensures small tolerances in the long term.

The correct oxygen content during ventilation is of fundamental importance, that’s why we are only satisfied with high-precision results.


Adapter set

Flexible in everyday life.

In mobile applications, flexibility is an important factor. Thanks to the large adapter selection of the CITREX adapter set, you can easily and correctly connect your test object. The precise intermediate elements offer particularly small spaces and minimal cross-section differences and allow high measurement accuracy and flexibility.

Improvised adapters are a thing of the past thanks to this set.
