Abstract : The apparatus includes a pressure chamber, a source of pressure, an oscillograph recorder and operating controls for the apparatus. The chamber has a load cell disposed therein, a pair of specimen holders one of which is fixed to the load cell and the other holder is mounted on a crosshead extension rod for slidable movement relative to the chamber. A pressure transducer is connected to the chamber and furnishes a pressure reading to the recorder. A galvanometer light beam monitors the preset test pressure level on the recorder and when the pressure reading from the pressure transducer reaches the recorder preset level the galvanometer activates a photocell to trigger the tester crosshead and thereby start the test.
