The RCBS Lead Bullet Casting Thermometer is a great accessory for any caster looking to have an accurate way to determine the temperature of their melted lead alloy. This thermometer measures between 200 and 1000 degrees Fahrenheit within 1 degree. The dial face features large numbers that are easy to read and the 6" handles is a great added safety feature so your hands don't have to be exposed to the high heat of the melted lead. The 6" probe was designed to work with the RCBS Pro-Melt furnace or pot but works equally well with other manufacturers casting furnaces. Notes: Comes with 6" handle, 6" long probe and 1-1/2" diameter dial face
