This apparatus consists of one glass component (the capillary tube) which is mounted on a strong backing plate, used to measure plant transpiration or environmental humidity.
It is ideal for laboratory and field use, allowing students to measure transpiration with minimal risk of breakages.
The capillary tube has a millimetre scale connected via a 3-way tap to a syringe, with the cut shoot connected to the third outlet.
To measure humidity, a porous pot is connected to the third outlet.
Dimensions: 15 x 7.5 x 19.5cm. The capillary tube is measured to 100mm with 1 mm graduations.
Qty: 1 potometer with manual.
