Designed to work with a computer or laptop, it automates indentation measurement, displays real-time results, tolerance values, and related test data, while still supporting manual measurement. ASTM E140 conversion tables, Excel export, and 2.5, 5, and 10 mm ball indentation support improve reporting accuracy.
NG-RockGen - Analogue Series Rockwell Hardness Tester - Manual and Electronic Models
NG-RockGen Analogue Series is a Rockwell hardness tester for routine hardness measurement of metals, available in manual and electronic models. It supports HRA, HRB, and HRC scales with a 10 kg preload and 60, 100, or 150 kg total test forces. Suitable for hardened steel, castings, aluminum alloys, bearing steel, and hard alloys, it provides practical shop-floor and laboratory verification.
NG-RockGen DGEN Series - Digital Rockwell Hardness Tester - Rockwell Regular, Rockwell Superficial and Rockwell TWIN Digital Models
NG-RockGen DGEN Series is a digital Rockwell hardness tester for measuring metal hardness by indentation depth under standard Rockwell loading. Available in regular, superficial, and TWIN configurations, it supports common HRA, HRB, HRC, N, and T scales, automatic test cycles, LCD readout, 0.001 resolution, built-in printer, RS-232 output, and repeatable testing for steel, castings, alloys, and bearing materials.
GenRock NG-150 Series - Advanced Rockwell Hardness Tester - Manual and Automatic Rockwell Hardness Testing System
GenRock NG-150 Series is an advanced Rockwell hardness tester for regular and superficial hardness testing of metals and alloys. Available in manual and automatic configurations, it supports ASTM E18, EN ISO 6508, and GB/T 230 workflows. Touchscreen operation, fast indentation cycles, arc correction, data storage, RS-232 output, and 0.001 resolution help laboratories improve accuracy, repeatability, and reporting efficiency.
NextGen Telebrineller Brinell Hardness Testing System
NextGen Telebrineller is a portable Brinell hardness testing system for field use, welding crews, and QA teams that need fast BHN checks outside a stationary lab. The complete kit fits in a lightweight case and uses a hammer-blow indentation method, impression measurement, and calculation support. ASTM E10 alignment makes it practical for weldments, castings, forgings, and large metal components.
Surface Roughness Testers
NextGen Surface Roughness Testers are portable profilometer-style instruments for measuring surface texture on machined parts and manufactured components. They help evaluate parameters such as Ra, Rz, Rq, Rt, and related roughness values that influence wear, coating adhesion, corrosion resistance, fatigue behavior, and functional performance. Compact operation, digital filtering, LCD display, optional sensors, and accessory platforms make them suitable for shop-floor and laboratory surface inspection.
UniGen Universal Hardness Tester – Rockwell, Vickers & Brinell Hardness Testing System
UniGen is an all-in-one universal hardness testing system for Rockwell, Vickers, Knoop, and Brinell measurements. Built for accurate, repeatable hardness testing, it combines a large touchscreen interface, closed-loop load-cell force control, automated test-force correction, and compensated loading without traditional weights. ASTM, ISO, JIS, and GB/T compatibility makes it suitable for laboratories needing multiple hardness methods in one robust platform.
Hardness Test Blocks, Indenters and Hardness Testing Accessories
Hardness test blocks, indenters, and accessories support daily verification and reliable operation of metal hardness testing systems. The range includes certified Rockwell, Brinell, Vickers, and Knoop blocks, along with diamond, carbide, ball, and specialized indenters, anvils, and accessories. ASTM- and ISO-aligned calibration options help laboratories confirm tester accuracy whenever scales, loads, indenters, or operating conditions change.
Metallography Consumables
Metallography consumables cover the materials needed for sectioning, mounting, grinding, polishing, etching, and cleaning specimens before microscopic examination. The range includes abrasive and precision blades, diamond cutting blades, mounting resins, phenolic resins, grinding papers, polishing cloths, diamond suspensions, lubricants, and etchants. These consumables help laboratories maintain consistent preparation quality, reduce surface deformation, and achieve cleaner, analysis-ready finishes.
