👉 Bromometrical is a system used in the measurement of temperatures, and it's based on the principle of thermometry. It involves measuring the temperature of a substance at different points or times using a thermometer, which can be either an electric or a gas thermometer. The process works by comparing the temperature readings taken from each point to find out how much the temperature has changed over time. In this system, the temperature reading is converted into a voltage difference based on the temperature differences between the two points
