Specifications and Product Details:

PHR Portable rockwell hardness tester

Equipment discription:

PHR Series Portable Rockwell / Superficial Rockwell hardness tester, is a reference to the foreign instrument, based on the basic definition of Rockwell hardness test design.

To meet the standard:

GB/T230.2-2004, the international standard ISO6508-1, American Standard ASTM E18, ASTM E110.PHR Series Portable Superficial Rockwell Hardness Tester has produced two specifications. Model PHR-1S and PHR-2S, the opening sizes are 1 inch (25.4mm) and 2-inch (50.8mm). They are to test the maximum thickness, or maximum diameter of 25mm and 50mm of the workpiece.
PHR Series Rockwell superficial hardness of the steel ball, diamond and Φ1.588mm two pressure head, with 15kg, 30kg, 45kg power of three tests, test HR15T, HR30T, HR45T, HR15N, HR30N, HR45N total scale of hardness 6 value, the test range from very hard to quench a hard steel, shallow carburization, nitriding steel to soft copper, brass, stainless steel, cold rolled steel plate, aluminum plate and so on. The measurement accuracy with national standard GB/T230.2-2004.
This hardness tester can also test a variety of small parts; various requirements of the workpiece indentation as small as possible; diameter as small as Φ2.5mm the rod material and the blade's hardness.

Hard materials with high hardness or thin. Such as cemented carbide, thin steel hardened, carburized hardened steel.Diamond indenterA60C
Low hardness materials.Such as annealed low carbon steel, stainless steel, copper alloy, hard alloy, malleable iron. Is to apply a broader Rockwell hardness scale.1/16 steel ballB100B
Quenching and tempering steel, as well as the general chilled cast iron, pearlitic malleable iron, titanium, etc.; hardness value of more than RB100 material. This is the most widely used Rockwell hardness scale.Diamond indenterC150C
Osmotic layer in the surface of hardened steel, thin hard steel, pearlitic malleable iron.Diamond indenterD100C
Cast iron, aluminum, magnesium alloy, bearing alloys.1/8 steel ballE100B
Annealed brass, copper, aluminum, mild steel sheet.1/16 steel ballF60B
Bronze, phosphor bronze, malleable iron, etc. (HRB value of nearly 100 materials).1/16 steel ballG150B
