Product Description

Unlike most conventional fridge thermometers the FM25 wireless fridge thermometer's technology allows you to view temperatures of food without opening the refrigerator door!

Temperatures from the remote RF sensors positioned inside your fridge or freezer are transmitted wirelessly and displayed on the base station which can be mounted magnetically to the cabinet or free standing using the fold away bracket. The display is updated every 8 minutes.

The FM25 audible and visual alarms are triggered when temperature exceeds pre-set maximum and minimum temperatures after 15mins (this prevents false alarms when door opened for loading) - alerting you to high or low temperatures that could affect the product quality.
