Expand your Weber iGrill Mini and Weber iGrill 2 with the Weber iGrill Pro Meat Sensor. Insert the pen into the meat. The sensor is connected to the iGrill Mini or iGrill 2. This means that you can be informed of the temperature of the meat via the app on your smartphone or tablet. When you have more meat sensors attached to the app, it is useful to give each sensor its own color with the supplied color indicators. So you see on the app exactly which piece of meat has reached the right temperature.Please note: this product is not a meat thermometer. It is only an extension of the Weber iGrill Pro Meat Thermometer.
