Yarn Package Hardness Tester HP-10-F

Textile hardness tester (durometer) to determine winding density of very loosely wound bobbins with thick yarns, such as carpet yarns

Indentor - ball diameter 10 mm
The measuring force is according to shore A regulations

Durometer with large working face for bobbins with more than 400 mm diameter

Special Features


The spring loaded outer ring assures a constant measuring pressure and eliminates false readings due to difference between operators

Ball shaped indentor prevents damage to bobbins

Flat bottom prevent tilting and improves the measuring accuracy

Adjustable Min. / Max. indicator marks to highlight working range of the yarn package hardness tester HP-10-F

For bobbins with diameters smaller than 400 mm use textile durometer HP-10 with curved working face

Optionally available: Calibration certificate with calibration report

Standard Features


High repeatability

Easy to use

Display range 0 – 100 hardness graduation marks

Certificate of Compliance with the order 2.1 according EN 10204 is included

* Meets requirements of Shore A
** Spring load of outer ring to create constant pressure when outer ring is pulled to red marking

Operation
For measuring the hardness, the spring-loaded outer ring of the housing is pressed downwards until the edge of the ring meets the red marking on the housing. This ensures a constant pressure and prevents measuring errors.

General:
The principle used to measure textile hardness is based on measuring the resistance force of the penetration of a ball shaped indentor against the spool under a known spring load. The hardness scale covers a range of 0 – 100, were 0 is the smallest and 100 is biggest hardness. The measuring force and the principle relates to the specifications of rubber hardness tester Shore A.

Operation with a durometer

Please note:
There exists no international standard for adjusting and calibration of textile hardness. Therefore we have developed our own test-standard and procedures.
