The IQ120 pit controller precisely regulates the cooking temperature inside a charcoal pit for precision smoking! Based on the IQ110"s proven control technology, but with so many cool bells and whistles! As seen on Good Eats "Right on Que". Alton Brown said: "It"s so cool !!" * Digital display indicates actual cooking temperature and food temperature too! Knob is actually a digital encoder - rotate to select parameters or change values from user friendly interface, click to select. So much easier than a keypad! * Programmable - automatically change cooking temp based on food temp, or based on a time delay! Set alarms to indicate food is done cooking or cooking temperature is out of range. 12 settable parameters in all! A large bi-color "cheat sheet" on the back lists all parameters and provides a short reminder of what it does. So easy yet so powerful! * Leftmost display digit is a "virtual blower", rotating when the blower is rotating, providing feedback on how hard the unit is working. Indicates when the fuel is running low! Optional lid-off detection algorithm prevents unit from feeding the fire even more after a lid-off event! * Fits Weber Kettles and Smokey Mountains, Char-Broil Horizontals and Offsets, Brinkman Vertical, Vikings, or any cooker with a flat or spherical surface with a fire vent damper less than 5" in diameter. Everything included in kit for operation from AC power; operates from 12VDC cigarette lighter socket using optional adapter available separately.
