A range of radio linked frost alarms, from single point 'alarm only' links intended for temporary deployment through to permanently installed solar-powered multipoint ambient air temperature senders accurate to half a degree C is available.
The range covers the full spectrum of growers' requirements with regard to frost warning. Starting with audio alarm modules for small family farms and finishing with real-time automatic remote temperature display/controllers.
All systems have user adjustable temperature trip points with relay outputs for auto diallers or other alarm systems.
