Key Features:

• Structure of PHB-300 is compact and reasonable. Compared with PHB-200 Digital Magnetic Hardness Tester, PHB- 300 has smaller size and close weight.
• Turn on the magnetic switch, and fix the hardness tester on the measured workpiece, one key operation can automatically complete the loading, maintaining and unloading of the test force, which saves time and has good stability.
• Applying High-accuracy force transducer, advanced closed loop measurement and control motor loading technology to ensure accurate and reliable test force value and good uniformity.
• Applying rechargeable lithium-ion battery, convenient to dismantle and change, suitable for continuous multi shift production and multi day on site testing.
• The OLED display can show the test procedure status and real-time test force value, which is convenient for the operator to monitor the loading force process.
• Lighting is provided above the indenter for easy observation and selection of test position.
