HPSA-R For Nip / Rubber rollers and Cylindrical materials
The HPSA-R# series shore A Durometers are designed to measure the hardness of rubber coated rollers and other cylindrical materials.
For cots, pressure rollers and many other rubber coated rollers, etc. The correct Shore A hardness of the cots is a critical factor to get the desired yarn structure and quality. As cots are abrasive, the hardness should be checked from time to time as they age.
3 Models:
HPSA-R20 - roller diameters up to 40mm
HPSA-R35 - roller diameters up to 70mm
HPSA-R55 - roller diameters up to 110mm
- Constant-pressure indicating system assures uniform test pressure eliminating false readings due to differences between operators.
- Supplied in a foam-fitted carrying case.
- Operation is as easy as pressing the spring-loaded knurled aluminum shell down to the red line.
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. |
PTS-HP Durometer Test Stand
- Mechanical lever-operated test stand for use when precise positioning is required on the test sample (i.e. o-ring, etc.).
- Operation is as simple as rotating the lever until the shell on the durometer reaches the red line.
