The checking apparatus for injection- or infusion-type pumps comprises a glass piston syringe, a linear potentiometer whose spindle is rigidly connected to the piston of the glass piston syringe, a pressure transducer in communication with the syringe inlet, and an electronic computing and evaluating means connected through a water-filled tube to the glass piston syringe and presses water into the glass piston syringe at a predetermined delivery rate. The apparatus displays on three display panels. These important parameters can be measured quickly and precisely with the aid of said apparatus.
