Textile hardness tester (durometer) to determine winding density of loosely wound bobbins of synthetic fibers and closely wound natural fibers, yarns and threads

Indentor - ball diameter 5 mm
The measuring force is according to shore A regulations

Durometer with curved working face for bobbins with diameter up to 400 mm

 

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
 
Working face slightly curved to fit on small bobbins, working face radius 55 mm
 
Adjustable Min./Max. indicator marks to highlight working range of the yarn package hardness tester HP-5
 
For bobbins with diameters over 400 mm use yarn package hardness tester HP-5-F with flat working face e.g. warping beams
 
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
