Telebrineller hardness measurements are a direct comparison to a known physical reference, and therefore, measurements are not subject to inaccuracies due to alloy, thickness, geometry, position etc, that are common with many other portable testers.
The complete Telebrineller system, in its case, weighs approx 4.5 kg. Easily transported to any location, it is highly practical for all Brinell hardness testing needs.
One hammer blow, measurement of the resulting impressions and the manipulation of a basic equation on the calculator provided is all that is required. In a few minutes, anyone can learn to measure BHN accurately.
The test bars which are the core of this system, are calibrated to a uniform hardness of +/- 3% of the labelled 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 0.05 mm.
Designed for field use, there are no delicate adjustments or fragile components to be concerned with. All parts are rugged, solid and able to deliver accurate measurements in all weather, under the roughest field conditions.
The kit includes 5 bars of selected hardness, microscope, calculator, bar holder, calculation pad and carrying case.
