1, high measurement precision. For direct contact with the object being measured, not affected by intermediate medium.
2, wide measuring range. Commonly used kitchen thermocouple from 50 degrees - 1600 degrees below zero are continuous measurement, some special ovens thermocouple minimum measurable to - 269 degrees (e.g., gold iron nickel chrome), up to 2800 degrees (such as tungsten, rhenium).
3, simple structure, easy to use. Oven thermocouple is usually composed of two different kinds of metal wire, but is not limited by the size and the beginning of, outside to protect casing, which are very convenient.
