monitors air temperature and triggers a flasher alarm as the temperature drops toward
frost conditions. It is primarily used in orchards and vineyards that use helicopters to

temperature probe of the RFF Remote Frost Flasher can be monitored and logged by a GP-MC
datalogger on its RS485 Line.
As supplied, the unit flashes as follows:
These trigger temperatures are programmable.
