lbf in compression and tension, torque calibrations to 5 000 Nm (3,688 ft-lbf) clockwise
and counter clockwise.
Field service capabilities include force calibrations to 1,000,000 lbf in tension and
compression as per ASTM E4, torque calibrations to 5 000 Nm clockwise and counter clockwise,
linear calibrations of Extensometers with readouts as per ASTM E83 and calibrations of
Hardness Testers, Rockwell, Brinell and Micro as per ASTM E18, E10, E92 and E384.
