Feature: 1. HIGH ACCURACY MEASUREMENT: Thermocouples provide highly accurate temperature measurements that accurately reflect the operating temperatures of gas furnaces, boilers, and water heaters, ensuring that the equipment operates within the proper temperature range. 2. RAPID RESPONSE: Thermocouples are able to quickly sense temperature changes and convert the changes into electrical signals that are quickly reflected in the temperature control system, enabling gas furnaces, boilers and water heaters to quickly regulate temperatures and improve response time. 3. HIGH TEMPERATURE RESISTANCE: Thermocouples are made of high temperature materials, which can work normally in high temperature environments, withstand high temperature operation of boilers and gas furnaces and other equipment, and have a long service life. 4. NOT EASY TO CORRODE: The thermocouple material is not easy to corrode, and can cope with corrosive gases or liquids in environments such as gas stoves, boilers and water heaters to ensure long term stable operation. 5. SAFETY PERFORMANCE: Thermocouple as temperature measurement equipment, with explosion proof, waterproof, insulation and other safety performance, can ensure the safe operation of the equipment in the complex use of the environment, to provide reliable protection for the user.
