Electronic spirometer

1Electronic spirometerOverview

The SF-101 electronic spirometer is a highly applicable lung function testing instrument. This instrument adopts a wing type gas flow sensor, equipped with a low-power, high-performance microprocessor system and precision digital circuit. The instrument has sensitive response, high accuracy, stable performance, low power consumption, and can be continuously used with only two No. 5 batteries. It can be widely used in respiratory, pulmonary, and sports medical testing. This instrument is particularly suitable for physical health examination of primary, secondary, and tertiary school students.

twoElectronic spirometerInstrument composition, characteristics, and working principle

1. Instrument composition: SF-101 electronic spirometer, nozzle, non-toxic medical plastic threaded tube, wing type gas flow sensor, and external power converter.
2. Functional features: The instrument uses advanced low-power microprocessor technology, LCD display screen, and touch sensitive thin film panel switch technology. Display is intuitive, accurate, and easy to operate. The detection head adopts an infrared photoelectric flow sensor with high sensitivity and good test repeatability, which is particularly suitable for measuring gas flow in changing states. Low power DC power supply, external AC converters (AC 220V input,+3V DC output) can also be used. In situations with AC mains power of 220V, external converters should be used as much as possible.
