The GTSSI Large Infrared thermometer is one of our premium line products. It has a temperature range of -76°F to 932°F ( that’s -60°C to 500°C for all of our metric friends). The distance to spot ratio is the highest we carry, which is 16:1. The laser sights produce an eight-point circle around what you measure to ensure you have the highest accuracy. There is a type K probe connection on the side, which can read temperature simultaneously with the surface Infrared reading.
