Pressure
(Differential 1Kpa)
Accessory Pack
including Spirometer
This contains all the parts needed to achieve a stethograph and
a potometer. The stethograph is described in the resources of the Pressure
(Difference 1 KPa) sensor page. The potometer is achieved with a simple tube
system which bathes the end of a large leaf in water and measures the fall in
pressure of an air pocket adjacent to this water. Also included in the accessory
pack for the 1KPa Sensor is a Spirometer attachment.
