Product Description

Model SRRH-1S, SRRH-2S, SRRH-1ST Small Rockwell Hardness Tester

FEATURES:
Tests the superficial hardness of metals.
The test principle and accuracy comply to standard ISO6508.
With the bench stand it can be used on the desk as well as on site.
Tests the hardness of thin plates, slim tubes, thin shafts, small balls and small stampings, workpieces with small indentation, replacing Vickers hardness tester.
It is used for finish workpiece non-destructive hardness test directly. The small indentation is acceptable to most workpieces.
Traceable standard hardness block.
Indenter inspected with standard Rockwell hardness tester.
Test force calibrated with load cells directly traceable to national secondary benchmark.

TECHNICAL PARAMETERS:
Initial test force: 3Kg
Total test force: 15Kg, 30Kg, 45Kg (For SRRH-1ST 15kg only)
Indenter: 120° Diamond cone, Φ 1.588mm carbide ball, Φ 1.588mm steel ball (SRRH-1ST)
Accuracy: Meets ISO 6508, ASTM E18
Resolution: 0.5HR
Test range: HRN, HRT, HRW, HRX, HRY…etc. 15 scales.
Application range: All metals including iron, steel copper, aluminium, zinc, lead, tin, carburized steel, nitride dsteel etc.

Model SRRH-45 Digital Superficial Rockwell Hardness Tester

Description:
Hardness Testers are based on the same construction principle of the COMP series which are already well known for their economy, reliability and ease of use. The measuring device consists of a micrometer gauge with manual zero setting. The108mm dial with either Rockwell standard or superficial scale(150-100-60Kgt) (15-30-45Kgt), allows direct reading of 1 unit and of 0.2 Rockwell units.
The loads may be selected by means of a knob ergonomically placed on the right side of the instrument.
Tests are carried out manually by operating the lever on the right side of the instrument, once the operator has displayed the correct pre-load application on the dial gauge and set the scale to zero by the dial gauge external ring.
By means of a knob on the lower left side of the instrument the operator can adjust the descent speed of the load applied.

Model SRRH-45DT Digital Superficial Rockwell Hardness Tester

Main Features
This series of hardness testers features high measuring accuracy, veliable performance and applicable to wide fields. By adopting the motor driven automatic loading and unloading technique, that thoroughly eliminates human error in those operations.
Model SRRH-45DT serves to determine the superficial Rockwell Hardness of hardmetals, carburized, nitrided layers, and other chemical freating layers, it is also used to for hardness test of thiner pieces.

Model SRRH-45S Digital Superficial Rockwell Hardness Tester

Description:

SRRH-45S Digital Superficial Rockwell Hardness Tester adopts novel-designed large LCD screen to display, as well as menu structure. It mainly functions are as follows:
1. Selection of Rockwell hardness scales.
2. Exchange hardness values among hardness scales.
3. Output the results of hardness measurement with printer.
4. RS-232 hyper terminal setting is with good reliability, excellent operation and easy watching.

Usage Range:
Surface hardened steel, surface heat treating and chemical treating materials, copper, aluminum alloy sheet, zinc layers, chrome layers, tin layers, bearing steel, cold and hard casting parts, etc.
