1. INTRODUCTION
Thank you for choosing the PHYTOS 31 Leaf Wetness Sensor from METER Group.
The PHYTOS 31 measures leaf surface wetness by measuring the dielectric constant
of the sensor’s upper surface (
). It has a very low power requirement, which
allows for many measurements over a long period of time with minimal battery usage. This
sensor also has very high resolution, which detects very small amounts of water (or ice).
The PHYTOS 31 does not need to be painted before use, eliminating the need for individual
sensor calibration.
Prior to use, verify the PHYTOS 31 arrived in good condition.
