Product Details
Ultrasonic Oxygen Sensor KGD - GAS - 425
Product Introduction
The Ultrasonic Oxygen Sensor KGD - GAS - 425 is a medical - grade
oxygen sensor developed based on the ultrasonic principle, used for
measuring the oxygen concentration in binary gases. It differs from
traditional electrochemical oxygen sensors in that it has a service
life of over 5 years, features automatic calibration and requires
no maintenance throughout its life cycle. It can detect flow rates
ranging from 0 - 80 L/min and has a response time of only 10
seconds. It is suitable for devices such as ventilators and
humidified oxygen therapy devices.
Product Features
