Portable Hardness Tester HLN-11A

Product catalog summary

Technical Specifications

The HLN-11A Hardness Tester measures material hardness across multiple scales including D/DC, D+15, C, DL, and G. The measuring ranges for these scales are as follows:

D/DC (LD): 170-900
D+15 (LD+15): 330-900
C (LC): 350-960
DL (LDL): 560-950
G (LG): 200-750

The device supports direct hardness measurement with stable support and compact coupling, ensuring reliable readings. Key parameters such as minimum weight and thickness of test pieces, minimum case hardened depth, indentation diameter, and indentation depth are considered for accurate testing, although specific numeric values are not fully detailed in the document.
