Not only is it an extremely safe idea to properly regulate the temperature of your food, it`s also the law. If the right kind of food doesn't stay hot or cold enough for long enough, you risk the spread of pathogens that may cause illness in your diners. Having a dial thermometer, such as the ones shown here, is the best approach to ensuring that your food stays at the proper temperature at all times. We offer both wall thermometers for regulating a smokehouse or walk-in refrigerator as well as smaller thermometers for individual dishes.
