Ultrasonic Oxygen Flowmeter KGD - GAS - 423 for High - flow Humidified Oxygen Therapy Devices
Product Introduction
The Ultrasonic Oxygen Flowmeter KGD - GAS - 423 is a five - in - one combined sensor based on ultrasonic technology. It can simultaneously measure flow rate, oxygen concentration, atmospheric pressure, temperature, and humidity, with a flow range of up to 240L/min. It is applied in high - flow humidified oxygen therapy devices, medical ventilators, and the detection of binary gases including oxygen. It has the advantages of high accuracy, fast response, no drift, no need for regular calibration, and maintenance - free.
