Product Overview
Our multi-function Brinell-Rockwell-Vickers hardness tester series integrates three mainstream hardness testing functions in one unit, including two configurations:
1. HBRVS-187.5: Weight-loaded mechanical model (stable and cost-effective)
2. 420HBRVS-187.5: Electronic closed-loop fully-automatic model (high-end intelligent touch-screen version)
Both models support one-click multi-hardness scale conversion, digital direct reading, and comply with global standards GB/T 231.2, GB/T 1172, ISO 6506-2, ASTM E10/E18/E92. One tester replaces three independent single-function instruments, greatly saving purchase cost and workshop space for multi-scene industrial hardness inspection.
Core Advantages
Universal Three-in-One Testing
Integrates Brinell, Rockwell and Vickers hardness testing, covering heavy workpieces, conventional metal parts and micro-indentation surface layers. Compatible with ferrous/non-ferrous metals, alloys, ceramics, plastics and heat-treated materials.
Two Loading Options for Different Needs
HBRVS-187.5 Weight-Loaded Version:
Classic direct weight loading with alloy steel levers and wear-resistant bearings. Zero electronic drift, ultra-stable long-term operation, ideal for cost-sensitive batch production.
420HBRVS-187.5 Electronic Automatic Version:
Closed-loop servo loading + 8-inch touch screen. Automatic loading-dwell-unloading, convex/concave surface automatic correction, out-of-range alarm, intelligent data storage and export, perfect for high-precision laboratory and automated production line testing.
High-Precision Digital Direct-Reading System
High-definition display eliminates manual reading errors. Supports Chinese-English bilingual switching, multi-hardness scale conversion, USB/RS232 data output, and optional upper-computer intelligent control system for standardized data management.
Wide Industrial Adaptability
Covers machinery manufacturing, metallurgy, auto parts, precision electronics, third-party testing institutions and scientific research laboratories, adapting to raw material inspection, process quality control and finished-product delivery testing.
