v line thermometer is a kind of instrument mainly used for measuring the temperature index of solid, liquid and gas of various instruments and equipment on ships. It is necessary for ships to go to sea. Therefore, marine thermometers should have: professionalism, rigor and accuracy, ease of use, on-site readability, stability, practicability, durability and other characteristics.
The main internal material of marine thermometers is mercury or various organic solutions. Their state will change due to different temperatures, so they can measure temperature. Because of their different properties, the data that can be measured with mercury as a material is better than that of organic solutions. Wider, more extensive uses.
