Product Description

Rockwell Twin Hardness Tester RH-100RS

1.Technical Data

Technical parameters of Rockwell hardness
Rockwell hardness test force
->  Preliminary test force (Tolerance: ± 2.0%): 98.07N (10kg)                
->  Total test force (Tolerance: ± 1.0%): 588.4N (60kg), 980.7N (100kg) 1471N (150kg)
indenter: Diamond cone indenter, Ф1.5875mm ball indenter
Metallic materials testing applications, the most commonly used scale is A, B, C.
In conformity with the above principles should be preferred.

Rear sight	Indenter	Total test fore	Reference symbol	Effective range
C	Diamond cone	1471N(150 kgf )	HRC	20 ~ 70 HRC
A	Diamond cone	588 N(60 kgf )	HRA	20 ~ 88 HRA
B	1.588  Ball	981 N(100 kgf)	HRB	20 ~ 100 HRB

 
C scale indenter is 120 ° diamond cone total test force of 1471 Newtons 150 kg force,for the determination of heat-treated steel products
A scale indenter is 120 ° diamond cone total test force is 588.4 Newton 60 kg force, for the determination of hardness exceeding 70HRC metals such as tungsten carbide, etc. can also be used to determine the hard sheet material and a thin surface layer hardness.
B 1.588 scale indenter ball diameter of 980.7 total test force Newton 100 kg force, for the determination of soft or medium hardness of the metal and non-hardened steel products.

It should be based on the type of sample material or estimates select the appropriate hardness scale of hardness measurements. Beyond the corresponding measuring scale measurement range can cause reduced accuracy or damaged head.

2.Superficial Rockwell hardness test basis
Superficial Rockwell hardness test principle and test methods and Rockwell hardness tester is basically the same, except that the test force loading and formulas.Press table selection of test parameters when Rockwell test

Rear sight	Indenter	Total test force	Reference symbol	Effective range
15N	120°Diamond cone	147 N   15 kgf	HR15N	70 ~ 94 HR15N
30N	120°Diamond cone	294 N   30 kgf	HR30N	42 ~ 86HR30N
45N	120°Diamond cone	441 N   45 kgf	HR45N	20 ~ 78HR45N
15T	1.588  Ball	147 N   15 kgf	HR15T	62 ~ 94HR15T
30T	1.588  Ball	294 N   30 kgf	HR30T	15 ~ 82HR30T
45T	1.588  Ball	441 N   45 kgf	HR45T	8 ~ 76HR45T
