HP SERIES Shore Durometer
The HPS Durometers measure the hardness and/or firmness of parts and test samples, e.g. rubber parts, plastic, elastic materials, textiles, printing rolls etc.
This unit is designed in accordance with ASTM and DIN quality standards which specifies the bottom contact area (working diameter), sensing pin configuration and internal spring forces. Additionally, the displacement of the sensing pin, relative to the dial indicator, is specified by these standards.
The HPS gauges work with an analog dial indicator calibrated for a range of 0-100 Shore units.
Min/Max markers are available to provide a visual indication of the acceptable hardness range.
All Checkline Durometers feature a unique spring-operator test pressure shell, which helps insure that similar test pressures are used for each measurement. This system significantly enhances the measurement repeatability, especially between different operators.
Oversized flat bottom surface makes the position of the working face (area of contact as specified in ASTM/DIN Standards) convenient and consistent which limits variability between operators.
Available Scales: A, B, C, D, DO, O
Conforms to ASTM D-2240.
Measuring Suggestions
| 1. | Whenever possible, a Durometer measurement should be taken at least 12 mm (approx. 0.500") in from the edge of a sample, as the hardness characteristic of any sample tends to change at the edges. |
| 2. | Whenever possible, the thickness of a sample should exceed 6 mm (approx. 0.250"). If the sample is thinner than this, then the sample can be backed with a sample of the same material to increase the thickness. |
| 3. | Test Coupons or test blocks (rubber or plastic) should not be used for calibration verification. As all samples are subject to characteristic changes over time along with temperature and lighting conditions, the rated Shore value when supplied as new can and will vary with age. Proper calibration verification requires independent confirmation of the internal spring forces along with the verification of the pin displacement vs. the indicated value on the scale. |
