The EMDxxx Forward Rate of Growth (FROG) sensor (patent pending) integrates the EMOxxx module in a ruggedized unit with built-in power source and preset thermostat trigger.   When used in tandem with the EMRxxx or EMRGxxx rover models this provides real-time data on conditions at the head of an active wildfire front where it is normally too dangerous for firefighters to work.

 

The unit is disposable, has non-rechargeable alkaline batteries and is equipped with a streamer designed to be air-dropped from a helicopter.
