Digital Double Rockwell Hardness Tester,Hardness Test Machine HRSS-150

MODEL HRSS-150 Digital Double Rockwell Hardness Tester

Description

1). The Digital Double Rockwell Hardness Tester adopts sensor closed loop control technique; it can test Rockwell, Superficial Rockwell and plastic Rockwell scale plate with good reliability, excellent operation and easy watching.

2). Here are the major functions:

2.1) The selection of Rockwell Hardness Scales: HRA,HRB,HRC,HRD,HRE,HRF,HRG,HRH,HRK,HRL,HRM,HRR,HRP,HRS,HRV,15HRN,30HRN,45HRN,

15HRT,30HRT,45HRT

2.2) The test force will be adjusted according to the scale plate by it self.

2.3) It can be transferred to all kinds of hardness scaleplate---Rockwell, Vickers, Brinell.

2.4) The errors of hardness values can be revised by pressing input keys; therefore, it enables the hardness values measured more precisely to meet the needs of test requirements.

2.5) The hardness testing results can be printed, outputted, and saved automatically. It can calculate erroers,Max,Min,Adv.

2.6) RS-232 hyper terminal setting offers clients expansion function.

2.7).Operative norm: GB/T230.1,? GB/T230.2,? JJG112
