Use to monitor the level of surface moisture on foliage, with range from 0
(completely dry) to 15 (saturated). Add up to 2 sensors to a single Wireless
Leaf & Soil Moisture/Temperature Station. Includes 40' (12 m) cable.
Compatible with both original Vantage Pro and Vantage Pro2.
The Leaf Wetness Part No: 04620
Sensor must be connected via a Leaf & Soil Moisture/Temperature Station.
The leaf wetness sensor (#6420) connects to the Wireless Leaf & Soil Moisture/
Temperature Station (#6345).
The Leaf Wetness Sensor detects the presence of surface
moisture.
The sensor is an artificial-leaf electrical-resistance type. It consists of
a sensing grid, low-voltage bi-polar
excitation circuit, and conductivity-
sensing circuit. The Vantage Pro2 console measures the conductivity
across the
grid and displays the result as a moisture level, scaled from
0 to 15. The user may select the threshold level at and
above which
moisture-hour totals are accumulated.
