These sensors measure the differential pressure between two ports. If one is left open, measurement will be relative to atmospheric pressure.
Blowing into one port will produce a positive value, whereas blowing into the other port will product a negative value.
Applications include:
- Experiments involving a Manometer
- Breathing rate (with LOG3462)
- Production of gases in an enclosed atmosphere during photosynthesis of an aquatic plant
- Osmosis investigations
- Rate of Transpiration investigations
