PESSL INSTRUMENTS LEAF WETNESS

Leaf wetness

Order number: 600015 / 900025 

The leaf wetness sensor works by measuring the conductivity on a filter paper, which is held between two stainless steel electrodes in a transparent holder. The use of transparent Lucite plastic as a holder reduces the warming up of the sensor when it is exposed to direct sunlight.
