Helivivfy Metal Hardness Tester – Portable Kit
The Helivivfy tester supports seven hardness systems, including HL, HB, HRA, HRB, HRC, HV, and HS, enabling versatile comparisons across steel grades. It is designed as a portable kit with a test block included, ideal for on-site work or small workshops. Materials supported cover steels, stainless steels, cast irons, and copper-based alloys. A data storage function can save multiple tests, aiding traceability and batch analysis. The device emphasizes ease of conversion between scales for quick assessments in production lines.
TSUBOSAN HRC/HB Hardness File Set
TSUBOSAN offers a file-style hardness reference set designed for quick checks and calibration. While primarily a reference tool, it provides practical resources for steel workpieces where in-house quick lookups are needed. The set is categorized for hardware work and is produced by TSUBOSAN FILE CO., Ltd. It suits shops needing physical hardness references to corroborate readings from handheld testers or calibration blocks.
7 in 1 Portable Leeb Hardness Tester – Soonkoda
This 7-in-1 device uses a D-type sensor for broad material compatibility and supports 10 materials, including stainless steel, alloys, copper, and steel variants. It automatically identifies the impact device when swapped and can switch between HV, HB, HRC, HRB, HRA, HL, and HS scales. A preset upper and lower hardness limit with audible/visual alarms supports batch testing, which is valuable for production lines requiring consistent material quality control. The instrument is designed for operator-friendly, field-ready use.
Mxmoonfree Digital Leeb Hardness Tester Kit
The Mxmoonfree kit emphasizes portability with a digital Leeb tester and a standard hardness block for calibration. It supports multiple scales and includes a rugged carrying case for safe transport. The calibration block and a small support ring facilitate precise measurements on small or awkwardly shaped steel parts. The device aims to provide straightforward operation and reliable results across common steel grades while keeping calibration within reach for field use.
SUNNYSONG Portable Hardness Tester
The SUNNYSONG tester integrates a built-in printer and color display, with data memory capable of storing up to 600 groups. It supports seven hardness scales and uses a standard D-type impact device, aligning with ASTM norms for portable testing. The internal lithium battery provides long operation life, making it suitable for fieldwork and shop-floor use where quick documentation is valuable. This model emphasizes easy data capture and reporting alongside its measurement capability.
VTSYIQI Leeb Hardness Tester – 10 Materials
The VTSYIQI meter reads HL, HB, HRB, HRC, HRA, HV, and HS, enabling broad steel coverage. It is housed in a compact plastic case suitable for challenging environments and awkward angles, including upside-down testing. A large segment LCD with backlight enhances field visibility. This model balances portability with multi-scale functionality, making it a practical option for workshops and job sites requiring rapid hardness verification of steel parts.
Buying Guide: Key Purchase Considerations
- Scales and material range: For steel-focused testing, prioritize devices offering HL, HB, HRC, HV, and HS, plus automatic scale conversion where possible.
- Portability vs. capability: Portable Leeb testers suit field work; benchtop systems or bundled kits excel in labs or shops with frequent calibration.
- Calibration and blocks: Look for calibration blocks traceable to standards, and ensure blocks are included or readily purchasable to maintain measurement accuracy over time.
- Data handling: Devices with internal memory or external data transfer simplify batch testing and traceability for quality records.
- Durability and ease of use: Compact cases, robust indenter assemblies, and clear displays support reliable long-term operation in industrial environments.
- Power and run-time: For fieldwork, check battery capacity and charging options; ensure the unit can operate for the duration of typical tests.
- Cost of ownership: Consider replacement indenters, calibration schedules, and availability of spare parts when budgeting.
In summary, the listed testers provide a spectrum of portable and semi-portable solutions with multiple hardness scales suitable for steel and alloy testing. When selecting, consider the balance between scale coverage, calibration support, data management, and the environments in which you will operate most often.
