HP系列

用於測量紗線卷、紗線束、紗線軸紗線圓錐體，染色包的繞線密度（硬度）

硬度測量的原理是基於在一個已知的彈簧壓力下，探針刺入被測物體的表面所受到的阻力，刺入程度轉化成硬度計表盤上的硬度值讀數。

功能特點：

1. 六種不同尺寸的球徑探頭和工作接觸面可供選擇

2. 恆壓力系統消除了由於操作者的差異造成的錯誤讀數

3. 球型探頭防止損傷線軸

4. 工作表面輕微的曲率適合於測量小徑線軸的硬度

5. 特殊的平面的接觸工作面適合測量直徑超過400mm的線軸的硬度

6. 還有情針可供選擇（型號M）

 *當外殼的底端被壓到與紅線重合時，則表示壓力達到恆壓力的要求。

產品特色：

d=2.5mm 球頭：適合高密度捲軸（e.g. 細絲、合成纖維）

d=5mm 球頭：適合中密度捲軸（e.g. 合成纖維、天然纖維、紗線、線）

d=10mm 球頭：適合低密度捲軸（e.g. 粗紗線、地毯纖維）

另有2.5-F、5-F、10-F 三款適合：測量直徑超過 400mm 之大型捲軸樣本

「恆定壓力環」提供穩定下壓力，避免不同測試者施力不均的問題

操作簡單、讀值準確、再現性高

Yarn Package Hardness Tester HP 2.5

Textile hardness tester (durometer) to determine winding density of closely wound bobbins of synthetic, finished fibers and filaments

Indentor - ball diameter 2.5 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 textile durometer
• For bobbins with diameters over 400 mm use durometer model HP 2.5-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

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.

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