Overview
LX-B type rubber hardness gauge is an instrument produced by HBO for medium Hardness rubber, thermal plasticity resilience, paper products, fiber hardness of materials measurement. When the hardness of materials is greater than 90HA and less than 20HD, this model is recommended. The hardness gauge supports handheld use and can also be used with a fixed load test bench.
Features
1. Suitable for medium Hardness rubber, thermal plasticity resilience, paper products, fiber materials.
The hardness of materials > 90HA, < 20HD is recommended.
3. Support both handheld and supporting bench usage.
4. According to the American ASTM D2240 standard, corresponding to the Type B hardness gauge.
Principle
This hardness gauge characterizes the material's Hardness by measuring the depth to which the pin is pressed into the material under test at a specific pressure. The pressure applied to the end of the pin varies from 0.55N to 8.05N, the pin Travel range is 0-2.5 mm, and the depth value is displayed as a Hardness value (HB) after being converted internally by the instrument.
Applications
Medium Hardness Rubber, thermal plasticity resilience, paper products, fiber materials
Standards
American ASTM D2240
Steps
1. According to the measurement requirements, choose handheld or installed on the matching LAC-J test bench for use.
2. Align the hardness gauge needle vertically and smoothly contact the surface of the tested sample.
3. Apply pressure so that the needle is fully pressed into the sample.
4. After the reading has stabilized, read the Hardness Value (HB) displayed on the display.
5. After the measurement is completed, remove the hardness gauge from the surface of the sample.
Notice
• Before measurement, it is recommended to calibrate the instrument with a Type B standard Hardness block.
• Ensure that the surface of the crimp and the tested sample is clean and flat.
• Keep the hardness gauge perpendicular to the sample surface and apply a steady pressure during measurement.
• This instrument is suitable for materials with Hardness > 90HA and < 20HD, beyond this range may affect measurement accuracy.
• Avoid use and storage in extreme temperatures or Humidity environments.
• Regular maintenance to ensure instrument accuracy.
