BASO Gas Products K19AT-30 30" Thermocouple

The BASO Gas Products K19AT-30 Thermocouple is a safety sensor specifically designed for gas-fired heating systems like furnaces and boilers. This thin, 30-inch-long wire acts like a temperature sentry, with the tip positioned directly in the flame. Despite its lightweight design (0.12 lbs), it plays a critical role. As the flame heats the tip, it creates a small voltage signal (25-35 millivolts) due to the temperature difference between the tip and the base of the thermocouple. This voltage signal is sent to the gas control valve, ensuring it receives the correct amount of voltage to regulate gas flow safely and efficiently. If your furnace is malfunctioning or experiencing gas flow issues, a faulty thermocouple could be to blame. Replacing it with the BASO K19AT-30 Thermocouple can restore proper gas flow regulation and ensure safe and efficient heating performance for your home.
