Grill thermometers give you instant temperature readings for your grilled items. Grill thermometers typically have pronged tips that allow you to insert the thermometer right into the center of meat. Grill thermometers come in various styles. Typical barbecue thermometers resemble a prong on a cord. The cord attaches to the thermometer display and the prong is inserted directly into the meat. Digital fork thermometers are steel barbecue forks that penetrate meat and display a temperature reading on the handle. Grill thermometers are also found combined with barbecue utensils like grill timers and grill tongs. Grill thermometers are battery operated and cost from $10 to $25 online.
