Multipoint thermometers simultaneously measure temperature in multiple locations, either horizontally or vertically, within a process. Horizontal measurements could involve reading multiple temperature points at some level across a batch reactor or process vessel. A vertical temperature profile could be composed of top to bottom measurements in a tank.
Environmental regulations and the need for better control propel increased use of such temperature profiling in many process applications.
