The WeatherPAK monitors wind and weather patterns in emergency situations to provide data that can be seamlessly integrated into PlumeRAE software to predict the impact area of a toxic substance release. The top choice of first responders for 20 years, this monitor can be set up by one person in less than a minute with no tools. It is weather-proof, and impervious to most airborne chemicals, so it functions well even under harsh conditions. The rugged, ultra-sonic wind sensor is accurate at low wind speeds, and has no moving parts, while the WeatherPAK’s other sensors collect information on air temperature, humidity, and barometric pressure. With it’s integrated wireless transmitter, the WeatherPak can provide data to a remotely located command center and automatically computes and wind data and wind stability class, giving you a complete picture for informed action.
