Vantage Pro2™
The Vantage Pro2™ (# 6152C) and Vantage Pro2™ Plus (# 6162C) cabled weather stations include two components:
the Integrated Sensor Suite (ISS) and the console. The ISS contains the sensor interface module (SIM), rain collector,
an anemometer, and a passive radiation shield. The Vantage Pro2 console provides the user interface, data display,
and calculations. The Vantage Pro2 Plus weather station includes two additional sensors that are optional on the
Vantage Pro2 and purchased separately: the UV Sensor and the Solar Radiation Sensor. The console and ISS are
powered by an AC-power adapter connected to the console. Batteries can be installed in the console to provide a
backup power supply. Use WeatherLink® to let your weather station interface with a computer, log data, and upload
weather information to the Internet. The 6152C and 6162C models rely on passive shielding to reduce solar-radiation
induced temperature errors in the outside temperature sensor readings.
