Measuring contact angles on leaves at different relative humidity using DataPhysics HGC
The influence of relative air humidity on the wettability of plant leaf surfaces can be studied with a combination of our humidity generator HGC and optical contact angle measuring device OCA. The following note uses Miscanthus leaves as an example to present this technique.


DataPhysics HGC product series
The humidity generators and controllers of the HGC series allow for a reliable control of the relative humidity, in the range of 5 % to 90 %, inside small environmental measuring chambers.
