HLN-140 Portable Leeb Hardness Tester
Product Overview
The HLN-140 Portable Leeb Hardness Tester is a lightweight, handheld hardness inspection device for on-site rapid metal hardness testing. It supports 7 interchangeable impact devices with automatic identification without recalibration, compatible with multiple hardness scales. Compact and durable, it is widely used for large heavy workpieces, installed components and narrow-space testing scenarios, complying with the international standard GB/T 17394.2.
Core Advantages
Multi-Impact Device Compatibility
Supports 7 types of interchangeable impact probes, automatically identifying device types with no recalibration required after replacement, adapting to diverse workpiece testing demands.
360° Omni-Directional Measurement and Intelligent Batch Testing
360-degree free measuring direction for complex workpiece surfaces. Pre-set upper/lower hardness limits with automatic out-of-range alarm, ideal for batch quality inspection.
Large-Capacity Data Storage and Efficient Data Management
Stores 48-350 groups of testing data, including single-point values, averages, test date, impact direction, material and hardness scale. Equipped with USB data communication interface and supporting PC software for data export and analysis.
User-Friendly Intelligent Operation
Intuitive menu-driven LCD operation with built-in operation prompt function. Features indication calibration for stable and long-term accurate measurement.
Ultra-Long Battery Life for On-Site Use
Built-in high-performance lithium battery with over 500-hour continuous working time (without backlight), stable for long-time outdoor and workshop on-site testing.
Multi-Scale Hardness Conversion
Supports Leeb HL, Brinell HB, Rockwell HRA/HRB/HRC, Vickers HV and Shore HS hardness scales, one-click conversion for diversified material testing.
