The kymograph is a standard laboratory measuring device that can record a variety of phenomena. Its inventor, German physiologist Carl Ludwig (1816-1895), used it to record arterial blood pressure. Kymographs consist of a drum, which rotates at a steady speed. An arm holding a pen or stylus then moves in response to the phenomena. It records the results on the drum over a period of time. This kymograph is fixed to a trolley and is powered by mains electricity rather than batteries or clockwork.

Measurement is the process of estimating the magnitude of some attribute of an object, such as its length or weight, relative to some standard (unit of measurement), such as a meter or a kilogram. The act of measuring usually involves using a measuring instrument, such as a ruler, weighing scale, thermometer or speedometer which is calibrated to compare the measured attribute to a measurement unit. Metrology is the scientific study of measurement.
