With the MATC Freezer Thermometer, monitoring temperature changes in your freezer will never be easier. Our temperature indication devices and fridge thermometers provide accurate results within 0.5 degrees Celsius, maximizing the freshness and avoiding freezer burn.  If the freezer is too warm, the food’s taste and appearance will deteriorate. The warmer the temperature, the quicker this will happen. If the freezer is too cold some of the excess cold air may divert into the fridge portion of your appliance, changing the temperature there as well. Food stored in the freezer slowly loses hydration over time. If the freezer temperature is set too cold this dehydration process will become more rapid and the freezer storage life of your food item will be shortened. Fluctuating freezer temperatures can result in the growth of large ice crystals, creating an undesirable change in texture.  In order to ensure food quality, your freezer should be set to -20 °C (-4°F) to -18° (0°F).  With the introduction of the MATC Freezer Temperature Indicator you can avoid the spoilage of your food on a daily basis.
