Micro Precision has the Universal Calibrating Machine, which can calibrate force instruments up to 1000 lbs. using dead weight, which is a specification of .005% of range. The calibration is performed in both compression and tension.
Micro Precision has a Universal Testing Machine for Tension and compression 0 to 400,000 lbs. This is a versatile machine in which using ultra-precision load cells and the instrument to be calibrated are positioned in the machine and loaded in series with a mechanical force. The force is produced by a hydraulic activated precision pump specifically designed for calibration work.
Micro Precision has Portable calibration load cells to calibrate onsite tension and compression testers up to 3,000,000 lbs.
