Product Overview
The AOF1000 is an economical and practical ultrasonic oxygen sensor designed for detecting oxygen concentration, flow rate, and temperature. Utilizing ultrasonic wave propagation principles, it offers high accuracy, a long lifespan, strong anti-interference capabilities, a compact size, and rapid response. This sensor features full-range temperature compensation, low cost, high reliability, and ease of use, eliminating the need for regular calibration. Compared to traditional electrochemical oxygen sensors, the AOF1000 boasts a significantly extended lifespan with automatic, maintenance-free calibration. Its broad oxygen concentration detection range (0%~100%) makes it ideal for oxygen concentrators, specifically for detecting concentrations between 21% and 95.6%, making it a prime choice for oxygen concentrator OEMs. The AOF1000 is suitable for a wide range of applications in medical, industrial, chemical, mining, and food sectors, including medical oxygen concentrators, industrial oxygen production equipment, mining environment monitoring, and food storage and processing.
