Sensirion SFM3400: proximal flow sensor for neonatal and paediatric applications, ±33 slm bidirectional, low dead space, I²C output.
SFM3400 is a proximal flow sensor developed by Sensirion for neonatal and paediatric respiratory applications. It measures bidirectional flow up to ±33 slm with high precision, and its dead space below 1 ml makes it suitable for measurements on small patients. It is available as the single-use SFM3400-D and the reusable (autoclavable / washable) SFM3400-AW.
Key features
