For monitoring the temperature of your grill, you can use any leave-in digital meat thermometer. Choose a model that has a braided steel sleeve over its wires, designed to prevent crimping or melting where it touches the hot surfaces of the grill. Position the probe on the grates, without the tip touching metal, so that it measures the temperature at the cooking surface.
