The following accessories are designed for use with the Weather Monitor II.
• External Temperature/Humidity Sensor
Replaces the standard external temperature sensor. Allows you to mea-
sure outside humidity and dew point in addition to temperature.
Includes 40 feet (12.2 meters) of cable.
• Rain Collector
Enables you to measure daily and accumulated rainfall. Separate models
measure rainfall in either 0.01 inch or 0.2 mm increments. Optional Rain
Collector Heater allows you to measure freezing rain or the moisture
content of snowfall.
• WeatherLink

Software and Data Logger
Logs data gathered by the Weather Monitor II, downloads it to your PC

, and generates reports and graphical displays of your
weather data.
• Car/Boat/RV Lighter Cord
Uses the cigarette lighter in your car, RV, truck, or boat to power the
Weather Monitor II. Replaces the standard AC-power adapter.
• Sensor Mounting Arm
A single-location mounting option for all your sensors. Includes posi-
tioning for anemometer, external temperature or temperature/humidity
sensor (with Radiation Shield), and Rain Collector (with Rain Collector

• Radiation Shield
Protects the temperature or temperature/humidity sensor from the sun
and the effects of radiated and reflected heat. Increases the life of the sen-

(RFI), electrostatic discharges (ESD), and power surges that can come
through sensor wires. Replaces junction box included with the station.

(12 m) or 100 feet (30 m)] for use with the anemometer, external tempera-
ture sensor, Rain Collector, or WeatherLink. Order the 6-Conductor
Extension Cable [in lengths of 40 feet (12 m) only] for use with the Exter-
nal Temperature/Humidity Sensor.
• Junction Box Cables
Order a Standard 8-Conductor Cable for greater flexibility in the place-
ment of your console. Comes in lengths of 25, 50, and 100 feet (7.6, 15.2,
