Digital Rockwell Hardness Tester
A hardness tester is a device that determines a material’s hardness by measuring the effect of a localized penetration by a standardized rounded or pointed indenter made of diamond, carbide, or hard steel on its surface.
The Rockwell hardness tester measures hardness by measuring the depth of penetration of the indenter under a defined load with either a steel ball or a conical diamond known as a brale. The matching hardness number is given on a dial, and this depth is relevant to the position under a minor beginning load. Rockwell testers with brale indenters are particularly suitable for hardened steel.
TESTRON Introduce TTR-45D Digital Superficial Rockwell Hardness Tester:
- TTR-45D is a half automatic and intelligent hardness testing machine, except to lift up the anvil to touch the specimen and select the test force: 15Kgf (147.1N), 30Kgf (294.2N) and 45Kgf(441.3N) in hand-knob manually, the other operations are entirely automatic.
- The testing force, the process of loading, dwell and unloading, the hardness testing value, and the corresponding converted scale are displayed on LCD screen automatic.
- TTR-45D system will remind the operator to select the corresponding testing force and indenter after scales choosing, and the automatic hardness testing and digital 0.1HR resolution display avoids the man-made error and enhance the measuring accuracy.
- TTR-45D force knob adopts the metal material to replace the plastic material, it improves the instrument using-life greatly.
- TTR-45D can make the hardness conversion among 14 hardness scales: HRA, HRB,HRC, HRD, HRF, HV, HK, HBW, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, it doesn’t need the operator to trace and check the fussy hardness comparison table again.
- TTR-45D saves, displays and analyzes the value of maximum, minimum, average and tolerance automatically, the mini-printer prints the main measuring data automatically, and it supports PC communication in RS 232 interface and cable.
