This digital tool is provided for force calibration. Called the Gauge Buster Calibration Unit, it is designed to be combined with load cells to certify materials testing machines, presses, and other load weighing equipment to ASTM E4 Force Verification standards. Useful for calibrators and manufactures of force transducers, the unit stores up to ten load cell calibrations with 15 points of linearization in each calibration. The unit includes a remote pushbutton to freeze the current load and record it from the Gauge Buster display. Calibration results can also be imported into reports to produce certifications.
