Freezer Safe Tracks Fridge Temps
Palm-sized gadget lets you set thermostat for optimal performance.
No bigger than a pack of gum, Freezer Safe is a digital recording thermometer that collects temperature data and displays it graphically. The battery-operated (two AAA cells) unit can optimize boat refrigeration systems by storing high and low temps for 100 minutes, 100 hours, or 100 days (though the batteries might not last that long). The data lets you adjust thermostat settings in order to reduce power use. The thermometer can also track warm and cold spots and help you find the best trade-off between food longevity and temperature. Freezer Safe can warn you if food may have thawed and refrozen, helps reduce the risk of accidentally freezing refrigerated foods. For holding-plate refrigeration systems to operate efficiently, the temperature cutoff on the compressor must be carefully set. Freezer Safe can help identify the ideal eutectic point for this system.
