The temperature sensors belong to the category of measuring technology and serve to precisely determine the degree of heat of liquid of gaseous media. For many manufacturing and production processes, but also in research and development, in medical technology and the food industry, the temperature of the media, materials of substances used plays an elemental role. Food can become bad if the temperature is too high, for example, chemical compounds dissolve if the temperatures are wrong and some media go up in smoke, so to speak, if there is too much heat. A continuous and precise temperature monitoring and measurement is therefore essential in many areas. NieRuf offers a large number of different measurement devices for almost every area of application.
