Product Description

CCSi features this high quality Gibitre® Schob Type Pendulum Tester for evaluating impact resilience and penetration of rubber by means of a pendulum rebound, as described in ASTM D7121, “Standard Test Method for Rubber Property-Resilience Using Schob Type Rebound Pendulum.”

The Model G—PRT features automated operations and the mechanical mechanism greatly simplifies the testing procedure, reducing technician intervention and producing accurate, precise and reliable results.

The resilience measurements are accurate, reliable, repeatable, reproducible and as easy as 1—2—3!

  1. Insert the specimen,
  2. Release the Pendulum Arm,
  3. Remove the specimen.

The test determinations are automatically DISPLAYED, STORED, MEAN CALCULATED and the RESULTS PRINTED!


The Gibitre® Schob Pendulum Rebound tester features microprocessor calculation of the mean value of the test determinations performed. It also features a large backlit LCD data / function display located on the console unit.


The Model G—PRT has an integral thermal data printer for producing a “hard copy” of test results . It is available with an optional RS—232C serial port for connection for data transmission, storage and retrieval.
