14 Davis Instruments
1. Solar Radiation Sensor
To measure solar radiation and solar energy.
Diffuser element and housing are carefully
designed for accurate cosine response. Silicon
photo diode provides good match to solar
spectrum. Two-piece housing minimizes radiation
heating, allows convection cooling of the sensor,
and prevents the trapping of water or dust. To
mount next to a rain collector, add our Sensor
Mounting Shelf (not included).

Includes 2 ft. (0.6 m) cable. Use Standard 4-Conductor
Extension Cable. Maximum cable length is 125 ft. (38 m)
from sensor to integrated sensor suite.
2. UV Sensor
Measures the sunburning portion of the UV
spectrum. Allows you to display UV index, dose
rate, and daily and accumulated dose. Multi-
layer filter provides a spectral response that
closely matches the Erythema Action Spectrum.
Diffuser provides excellent cosine response.
Two-piece housing minimizes radiation heating,
allows convection cooling of the sensor, and
prevents the trapping of water or dust. To mount
next to a rain collector, add our Sensor Mounting
Shelf (not included).

3. Sensor Mounting Shelf
For mounting solar radiation and/or UV sensors.
Rigid shelf with anodized aluminum posts and
stainless steel hardware attaches easily next to
the rain collector on the outside of the Vantage
Pro2 Integrated Sensor Suite.

4. Soil Moisture Sensor
Watermark
®
soil moisture sensor uses electrical
resistance to measure the moisture level of the
soil. Does not require periodic maintenance
during the growing season. Simply bury at the
desired depth, then monitor moisture levels
throughout the season. Add up to four sensors to
a single Leaf & Soil Moisture/Temperature Station.
Includes 15 ft. (4.6 m) cable.

8. Anemometer
Includes both wind speed and wind direction
sensors. Rugged components stand up to
hurricane-force winds, yet are sensitive to the
lightest breeze. Wind-tunnel tested to speeds in
excess of 180 miles per hour. Sealed stainless
steel ball bearings for long life. Comes complete
with mounting hardware.

Includes 40' (12 m) cable. Use Standard 4-Conductor
Extension Cable. Maximum cable length is 240' (73 m)
from anemometer to sensor interface module. See page
17 for extension cable options.
9. Leaf Wetness Sensor
Use to monitor the level of surface moisture
on foliage, with range from 0 (completely dry)
to 15 (saturated). Add up to two sensors to a
single Wireless Leaf & Soil Moisture/Temperature
Station. Includes 40 ft. (12 m) cable.

10. Rain Collector
Designed to meet the guidelines of the World
Meteorological Organization, our self-emptying
rain collector with tipping bucket is exceptionally
accurate. Measures in 0.01" or 0.2 mm
increments. Includes 40 ft. (12 m) cable.

Uses standard 4-conductor extension cable. Maximum
cable length is 900 ft. (270 m) from rain collector to
console, including junction box cable. See page 17 for
extension cable options.
11. Universal Anemometer Interface
Now you can use an R.M Young or NRG
anemometer with your Davis system. This
interface adapts certain third-party anemometers
to report to a Vantage Pro2 Integrated Sensor Suite
or Anemometer/Sensor Transmitter Kit. It has been
tested with the R. M. Young anemometer model
number 05103 and with the NRG anemometer,
model 1900 NRG #40C. However, the interface is
not limited to those products. Solar powered with
lithium battery backup.
