Product Details
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.
Product Features
- Ultrasonic technology, maintenance - free and drift - free
- Simultaneous measurement of oxygen concentration and gas flow rate
- 2ms fast response to meet flow regulation requirements
- Full - range temperature and humidity compensation
- Service life of over 10 years
