HazMet is a slimmed-down version of our MAWOS developed for rapid deployment in then event of an accident where hazardous chemical or biological contaminants are released into the air. This basic, battery-powered system reports wind, temperature, RH, and barometric pressure and more. Here's partial list of features:

•  EPA Cameo/Aloha Data Format
•  Built in GPS with electronic compass
•  Battery or AC Powered; Solar power options available
•  Small, light weight, rugged, & easily deployed in under five minutes. 
•  Spread spectrum radio included
•  Operates unattended with virtually no maintenance
•  Built-in self-diagnostics & testing
•  LPAWOS and solar power options easily added 

OWI Weather Sensors

Our original research resulted in a series of weather sensors with unprecedented accuracy and reliability. In the years following we have refined and enhanced our analysis techniques. Combined with added features and improved electronics, our weather sensors now offer the most value for you - ever.
