Product Description


Oxygen Sensor Detects Oxygen ConcentrationOxygen sensor is aimed for oxygen concentration and flow rate monitor.It adopts ultrasonic technology with high accuracy, strong anti-interference ability, rapid response, and long service life features.
Oxygen Sensor Detects Oxygen ConcentrationOxygen sensor is mainly used to detect the concentration of oxygen produced by molecular sieve oxygen concentrator. Our oxygen concentration detection device has features of simple structure, swift response and high measuring accuracy. The high/low oxygen concentration indicating dvice of our lambda sensor can be designed as an indicating lamp or a real-time digital display according to customer's preference. So far, our company has successfully produced customized oxygen sensors for many famous oxygen concentrator manufacturers. We are looking forward to your negotiations and cooperation.
