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.

Glossary: measurement

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.
