110-WS-25 Modular Weather Stations

From

0
The 110-WS-25 Modular Weather Stations are meteorological systems designed to be a 'user friendly' solution for data storage and real-time monitoring of weather conditions. The standard sensor package includes 6 weather parameters: wind speed and direction, temperature and relative humidity, barometric pressure, and precipitation, (additional optional sensors can be added), a 5-foot tripod and vertical mast for sensor mounting, and a data logger with LCD display.

Applications include hazmat/emergency management situations, fire management, and temporary meteorological surveys. The system is compatible with NOAA designed CAMEO/ALOHA Plume Modeling Software.

The basic system includes sensors for wind speed, wind direction, and temperature. Various other sensor options include, but are not limited to, relative humidity, barometric pressure, solar radiation, and precipitation. Two auxiliary channels are available for integration with gas monitoring sensors or other non-meteorological parameters.

The data logger includes 128KB RAM (approximately 45 days at 15 minutes intervals). Additional memory is available. The system is 12V battery powered with a 7AH battery that will operate for approximately five days between charging. A 110V battery charger/power supply is included. An optional solar panel is available. The data logger will communicate with Windows HyperTerminal Software for real-time monitoring of data and for data downloading. NovaLynx also offers several graphical display software programs.
