Ultrasonic Oxygen Sensor KGD - GAS - 422 Product Introduction The Ultrasonic Oxygen Sensor KGD - GAS - 422 is an economical and
practical sensor used to measure the gas flow rate in binary gases.
It features a small size, fast response speed, high accuracy, and
zero offset. Based on the mature Gasboard - 7500H ultrasonic oxygen
sensor, it is optimized and upgraded to replace and expand the
application of the original series in more scenarios. Product Features - Can simultaneously measure oxygen concentration and flow rate
- Full - range temperature compensation
- Small size, fast response, stable measurement, high accuracy
- Meets the requirements of special occasions such as medical use
- Long service life, maintenance - free
- Supports serial port output of accurate measurement values
