- Flowmeter: 0 L/min to 100 L/min, Accuracy: ±2%
- Micromanometer Range: -1000Pa to 1000Pa, Accuracy: 1Pa
- Air Pumping Volume: No less than 100L/min
- Ventilation Constant: (85±1)L/min
- Dimension: 380*620*825mm (Head model specifications: 30, 25, 20)
- Power Supply: AC220V, 50Hz
Features:
The instrument includes an adjustable flow air source, a standard human head model, and a dual-pipeline system for inhalation and exhalation resistance measurement. The flow sensor is highly sensitive with minimal starting flow, utilizing a thermal mass flowmeter that negates the need for temperature and pressure compensation, ensuring precise measurements. Multiple sensors on a single chip enhance the sensor’s range ratio. It offers high stability, accuracy, excellent repeatability, low power consumption, low pressure loss, and fast response speed. The data logger features a graphic dot matrix LCD with a resolution of 128×64, supporting both English and Chinese interfaces for ease of operation.
