Overview

WEATHERPAK®M weather stations are impervious to airborne chemicals and designed to be deployed directly in the hot zone. These models can be set up in less than 60 seconds, without tools, by one person wearing full protective gear. A WEATHERPAK M weather station can survive a 1.8 m (6 ft) drop to concrete and withstand a decontamination scrubdown, as well as many other environmental hazards.

Detailed Description

The WEATHERPAK M is a portable, self-contained weather station for rapid response such as HAZMAT and emergency response applications, and it is designed to be deployed by personnel in full protective gear. Assembly takes less than 60 seconds, and the system automatically begins making measurements and broadcasting data as soon as the tripod and canister are coupled. The weather station is completely sealed and built from corrosion-resistive materials, making it able to withstand harsh environments. Data is broadcast from the weather station to the display unit via 467.8000 MHz UHF or a 900 MHz spread-spectrum radio. Data is transmitted in the standard ALOHA message format for direct ingestion by third-party plume modeling software.

The integrated 2-D ultrasonic anemometer provides years of maintenance-free operation, while a GPS and electronic compass automatically correct measurements based on location and orientation. An onboard barometer and temperature/relative humidity sensor round out the measurement suite, exceeding the criteria for an EPA station for atmospheric measurements.

The WEATHERPAK M is easily transported and includes a hard-sided case for the canister and a carrying bag for the quick-deploy tripod.
