General Information of AO-09 Oxygen Sensor:

AO-09 is the Oxygen sensor of Saftty that is featured a long life and fast response. The high-quality AO-09 replacement sensor incorporates a molded body design, specific for medical use, so the AO-09 Oxygen sensor is also a medical Oxygen sensor. Best of all, the AO-09 Oxygen sensor costs less than the sensors it replaces, creating additional saving while providing superior quality. For further information on the AO-09 or any product in ASAIR’s complete line of medical Oxygen analyzers and sensors, please contact Saftty.

Each sensor from Saftty is rigorously calibrated and tested before leaving the factory to ensure and satisfy customers’ large-scale applications.


Applications of AO-09 Oxygen Sensor:

Saftty AO-09 medical Oxygen sensors are intended as an oxygen-sensing component of an oxygen analyzer that measures oxygen concentration in breathing gas mixtures in the following applications:

• Sensing device for oxygen

• Control device of oxygen concentrators

• Medical ventilators

• Anaesthesia equipment

• Incubators

The use is limited to system monitoring, so the AO-09 Oxygen sensor is also an Oxygen monitor sensor. The sensors are not suited for breath-by-breath analysis of breath gases. Please refer to the instructions for use. To avoid cross-infection, please strictly follow the instructions of the oxygen analyzer manufacturer.
