What Is An Oxygen Sensor And How Does It Work?

In this blog article, people will learn what an oxygen sensor is and how it works. People will also find out about the advantages of using such sensors in various medical equipment.

What is an Oxygen Sensor?

An oxygen sensor is a tiny electronic device that detects the level of oxygen in the air.

How do Oxygen Sensors Work?

An oxygen sensor is a device to measure the amount of oxygen in the air. The sensor uses an electrochemical reaction to determine the level of oxygen in the air. When the sensor detects low levels of oxygen, it sends a signal to warn the amount of oxygen that is being run out of.

Taking AO-07 as an example, talk about the characteristics and advantages of the Saftty oxygen sensor

AO-07 is Saftty’s medical oxygen sensor. This oxygen sensor has a molded body design and is designed for use in medical equipment and industrial scenarios. AO-07 medical oxygen sensor is an oxygen sensor component specially used for oxygen analyzers, which can be used in oxygen generator control devices, medical ventilators, anesthesia equipment, and other equipment to measure the oxygen concentration in a breathing gas mixture.
