• Probe: Made of durable alloy material, designed to be waterproof and rust-resistant, ensuring fine workmanship and longevity.
• Dial: Features a clear scale for intuitive and convenient reading of hardness measurements.
• Connecting Device: Allows for easier use when integrated with a testing frame, enhancing stability and measurement consistency.

3. Setup and Preparation

1. Unboxing: Carefully remove the durometer from its protective packaging. Inspect the device for any visible damage during transit.
2. Initial Inspection: Ensure the probe is clean and free from debris. Check that the dial moves freely and the needle rests at zero when no pressure is applied.
3. Environmental Conditions: For optimal accuracy, perform measurements in a stable environment, avoiding extreme temperatures or humidity.

4. Operating Instructions

This durometer is designed to measure the hardness of sulfur rubber and plastic products. Follow these steps for accurate measurements:

1. Hold the Durometer: Hold the durometer firmly with the probe perpendicular to the surface of the material to be tested.
2. Apply Pressure: Apply steady, firm pressure to the durometer, ensuring the entire contact surface of the probe is pressed against the material. The pressure should be applied quickly but smoothly, without impact.
3. Read the Measurement: Read the hardness value on the dial within 1 second of full contact. For materials that creep (deform over time), a reading after a specific time (e.g., 15 seconds) may also be taken, as per specific testing standards.
4. Repeat Measurements: Take at least five measurements at different points on the material, ensuring each measurement point is at least 6mm away from any other measurement or edge. Average the readings for a more reliable result.

Understanding Shore Types:

• Shore Type A: Suitable for general rubber, soft vulcanized rubber, natural rubber, soft resin, leather, wax, etc. (This is the current product type).
• Shore Type O: Used for soft materials such as foam, sponges, and very soft rubber.
• Shore Type D: Ideal for harder materials like general hard rubber, resin, acrylic, glass, thermoplastic rubber, printing plates, and fibers.

5. Maintenance and Care

• Cleaning: After each use, wipe the probe and the body of the durometer with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or internal components.
• Storage: Store the durometer in its original protective case when not in use. Keep it in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
• Calibration: While the device is designed for stable performance, periodic calibration by a qualified technician is recommended to ensure continued accuracy, especially if precise measurements are critical for your application.

6. Troubleshooting

If you encounter issues with your Hilitand Rubber Hardness Tester, consider the following common problems and solutions:

• Inaccurate Readings:
  • Ensure the probe is clean and free of debris.
  • Verify that pressure is applied perpendicularly and consistently.
  • Check for proper contact with the material surface.
  • Ensure the material thickness is sufficient (typically at least 6mm for Shore A).
• Needle Not Returning to Zero:
  • Gently tap the durometer to see if the needle frees up.
  • If the issue persists, there might be internal damage; contact customer support.
• Difficulty Reading Dial:
  • Ensure adequate lighting.
  • Clean the dial surface if it's obscured.
