طول المزدوج الحراري 300 SIT De Dietrich 95365380

A thermocouple length 300 SIT is a critical safety device for gas-fired heating appliances. It generates a small voltage to keep the gas valve open when the pilot flame is present, preventing gas leaks if the flame goes out. With a 300mm length, this thermocouple is suitable for many boiler and burner configurations where a standard reach is needed. Replacing a faulty thermocouple is a common boiler maintenance task that restores safe operation and peace of mind.
