P/2N 柱狀針型探頭

P/2N 直徑2 mm柱狀針型探頭
透過小針型或小柱型探頭進行穿刺試驗，適用於測試成品糧中的油菜籽、芝麻、葵花籽、油茶籽、棕櫚籽等較小的糧食顆粒，可得到顆粒的破裂強度（Break Strength）、硬度（Hardness）等。

Cylinder probes are used for puncture and penetration tests on gels, fruit, yoghurts and margarine to provide an index of Hardness, Firmness or Yield Points. A puncture test measures both compressive and shear forces. Properties such as viscoelastic creep, compliance and stress relaxation can also be identified.
