Product Overview:

      Ventilators are emergency medical devices and fall under the category of high-risk medical electronic equipment. The PF-300 Gas Flow Analyzer is currently the world's most advanced comprehensive quality testing instrument for measuring multiple gas concentrations in ventilators. With a strong contemporary appeal, it is highly favored by technicians. It is compact, highly precise, and user-friendly. The PF-300 features bidirectional flow, pressure, temperature, humidity, and oxygen concentration measurement capabilities, offering adult, pediatric, and high-frequency ventilation measurement modes. Therefore, the PF-300 is the ideal calibration tool for engineers.

Product Features

1. The user interface is designed based on detection parameters, making it practical, simple, and intuitive;

2. The main unit has built-in temperature and humidity sensors, automatically measuring gas temperature and humidity, and enabling automatic temperature and humidity compensation to ensure high-precision flow measurement, especially for stable measurement of low flow and low pressure, which is a standout advantage of the PF-300;

3. Breath Trigger: Supports both pressure and flow trigger modes to improve measurement accuracy;

4. Gas Standards: ATP, ATPD, ATPS, AP21, STP, STPH, BTPS, BTPD, and more.
