Hardness Tester - Mitech MH310

Leeb Hardness Tester MH310 Digital Hardness Meter Measuring Range 170~960 HLD Durometer

Product Overview:

The MH310 portable Leeb hardness tester is a versatile and efficient instrument designed for quick on-site hardness measurement of various metal materials. Its main features include:

1. Measurement Principle: Based on the Leeb hardness measuring principle, enabling fast and accurate on-site testing.

2. Scale Conversion: Supports free conversion between Leeb, Brinell, Rockwell, and other hardness scales, providing flexibility for different testing standards.

3. Display: Equipped with a high-contrast segment LCD for clear and stable display of measurement results.

4. Printing Capability: Features an integrated high-speed thermal printer, allowing on-site printing of test data for documentation.

5. Applications: Widely used in processes such as annealing, tempering, quenching, and quality control of workpieces; testing hardness of machine tools, automotive chassis, non-removable parts in service, hardware, forging, and special steels; and batch production quality control.

6. Cost-Effective and Reliable: Offers good quality at an effective cost, making it a suitable choice for regular hardness testing needs.

Overall, the MH310 is a reliable, convenient, and efficient solution for various industrial hardness testing scenarios.

Features:

• Multiple Impact Devices: One main unit can connect to up to 6 impact devices, supporting various testing scenarios.

• Steel Testing Support: When using the D/DC sensor, it can directly display HB (Brinell hardness) for steel testing.

• Automatic Calibration: Software handles automatic calibration, ensuring measurement accuracy.

• Data Storage: Stores up to 100 groups of measurements (impact times 32 to 1), including details like single test values, averages, date/time, impact direction, frequency, material, and hardness.

• Display: Features a high-contrast segment LCD with a bright EL backlight, with battery capacity and charge status indication.

• Auto Power Off: Conserves battery life by shutting down automatically when inactive.

• Built-in Printer: Equipped with a high-speed thermal printer for instant on-site documentation.

• PC Software (Optional): Supports measurement data transfer, storage management, and statistical analysis.

• Portability & Durability: Compact, stable, and reliable performance suitable for challenging field environments, resistant to vibration, shock, and electromagnetic interference.

This combination of features makes it ideal for precise, efficient, and durable hardness testing in various industrial and field applications.
