This kymograph is designed for recording mechanical activities of animal tissues in the physiological, pharmacological and biological experiments conducted by medical and pharmaceutical colleges or research institutes. It is with those characteristics: portable, solid, durable, runs noiselessly, steadily, reliably and reassuring. It can also shift rotational speed in a large range. The instrument is simply assembled and convenient to servicing. It can be assembled with a passive drum for being used as a two –drum kymograph.
