PHR SERIES OF CHAIN PORTABLE ROCKWELL HARDNESS (ROLL HARDNESS)
* A diminutive indentation, effort speed, without alteration to the workpiece crapper be at the environs for the ratio of the case-by-products of NDT.
* With a ratio of the commonly utilised hardness, Xiaoshi hardness compared to effort the quality of the machines more than double, a bourgeois moving the quality of effort less, the opencast closing Yaoqiubugao, without transmutation to the eld of the workpiece Product standards in planetary change easier acceptance of the advantages.
* Test continuance crapper be regenerate into Brinell hardness (HB) or the continuance of the tensile capableness (σ b).
* Tests allow illustrator HRA, HRB, HRC, much as 15 gauge, principles and standards in distinction with investigating the quality GB/T230, ISO6508, ASTM E18, nonachievement is inferior than ± 1.5HRC.
Hardness of the scale: illustrator hardness HRA, HRB, HRC, much as 15 gauge.
Test of: primeval effort of 10 kg
The effort of 60 kg, 100kg, 150kg
Accuracy: foregather the standards GB/T230, ISO6508, ASTM E18
