Product Overview:

        The Shenzhen Yice Medical Airflow Analyzer (VM-1) is an economical and efficient flow and pressure measurement device. It is compact, portable, user-friendly, and easy to operate, making it highly suitable for testing and calibrating medical equipment such as ventilators and other gas delivery systems. The VM-1 is equipped with multiple built-in sensors that can simultaneously measure flow, pressure, temperature, oxygen concentration, as well as key ventilator parameters such as tidal volume, respiratory rate, I:E ratio, peak pressure, PEEP, and more. It is an ideal testing device for ventilators.
