Telebrineller Test Bar
The Telebrineller system is a major achievement in quality assurance. This system is based on proven metallurgical knowledge supported by more than fifty years of field experience.
Certified Accuracy: The test bars which are the core of this system are calibrated to a uniform hardness of ¬±3% of the labeled BHN. Hardness of the bars is measured by equipment whose accuracy is certified traceable to the National Standards Institute. The Telebrineller microscope is by Leica. Readings may be made within .05 millimeters.
