Features

• The instrument consists of an air source with adjustable flow, a standard human head model, Inhalation and exhalation two-pipeline system, and a respiratory resistance measurement system.
• The flow sensor is with high sensitivity and very small starting flow.
• The flow sensor chip uses a thermal mass flowmeter, which does not require temperature and pressure compensation, ensuring high-precision measurement of the sensor.
• Multiple sensors are integrated on a single flow sensor chip, which greatly improves the range ratio of the sensor.
• The zero point stability of the flow sensor is high, it has the characteristics of high stability and high accuracy over the full range, excellent repeatability, low power consumption, low pressure loss and fast response speed.
• The data logger uses a graphic dot matrix LCD with a resolution of 128× 64 which is Chinese and English switching interface and easy to operate.
