Notes:

1Other capacities and diameters available on request. Calibrations that exceed geokon’s NIST traceable capacity of approximately 10,675 kN are subcontracted to an accredited testing laboratory.

2Established under laboratory conditions. System accuracy depends on end loading conditions.

3Other cable types, e.g., armored, are available.
