Resideo Q340A1066 Thermocouple you know that reuse ofThe Resideo Q340A1066 is a professional grade Universal 30mV Thermocouple designed for high reliability pilot flame sensing in standing pilot gas fired heating systems. This 18 inch thermocouple features a heavy duty construction with a focus on Maximum Copel content to ensure long term durability and consistent millivolt generation. When the pilot flame contacts the tip, the resulting temperature differential produces a stable 26mV 32mV open circuit
