The Vulcan Hart 00-412788-00048 Thermocouple 48\" T46 is an essential part to maintain better control of temperature and safe handling of the commercial kitchen appliances. This is a safety thermocouple used to sense the presence of a pilot flame to activate a small electrical current to keep the gas valve open when there is heat. In case the flame extinguishes, the gas supply is automatically switched off and this eliminates possible dangers. It has a 48-inch length and is accurate in performance and can be easily installed, and ensures effective and safe kitchen operations.
