The BHR-1A manual Rockwell hardness tester is bench mounted unit with a digital hardness display, providing conversion to other hardness scales and data recording with output function to PC, or wirelessly print test data to optional printer.
DSD series Digital Shore Durometer for testing the hardness of rubbers, elastomers and plastics. Available in Shore A for softer rubbers and Shore D for harder plastics, resins and other similar materials. Kit options are available for additional accessories.
The HTR-1000i portable LEEB hardness tester is used for general purpose metal hardness testing. It is compact and lightweight and can display results in a range of different hardness scales. Output results wirelessly via Bluetooth with the included dongle.
The HTR-1000s is a portable hardness tester ideal for a wide range of general use. The external, probe style impact device makes this unit ideal for use where access is limited, such as internal bores, recessed areas etc.
The LHT Series is an ultra compact Portable Hardness Tester with an integrated D-type LEEB impact device for general purpose metal hardness testing. C, DC, DL and G-type indenter versions are also available for difficult applications, please call us to discuss.
LHT-200 series LEEB Portable Hardness Tester includes a touch-screen PDA main processor unit, D-type indenter on fly-lead, calibration block and Bluetooth printer for quick data output. The LHT-200 is able to convert the results to many scales including HRC, HRB, HB, HV and MPa. Additional, optional indenters are available to cover an extended range of testing requirements.

Material hardness testers measure the hardness of materials. Hardness is defined as a material’s resistance to deformation, specifically resistance to being scratched, cut, bent, broken, or have its shaped changed when a load is applied. The greater the hardness of the material, the greater its resistance to deformation.
There are different scales used by materials hardness testers in terms of the weight of the load used. These are macro, micro and nano scales. Macro measurement is the simplest of the three scales that aims to gather hardness of a bulk material by testing only a small sample. In terms of weight load, the macro scale uses the heaviest load of the three scales and uses a specified deformable weight load, either the shape of a ball or a pyramid, to test for hardness. The micro scale is used for materials that are brittle and prone to cracking such as fiber glass. The nano scale uses very small amounts of load for even more brittle materials.
The TH-174 Portable Hardness Tester Complete Kit - TH-174C is a good example of a material hardness tester that uses the macro scale since it specialize in measuring the hardness of large and bulky materials. The Barcol-934 is a good example of a material hardness tester in the micro scale, given that fiber glass and similar materials are brittle and easily shatter. Lastly, the Digital Shore A Durometer - ICHF-SHRA is a good example of a nano scale tester given that it is only used in rubber and soft plastics.
