Cone/Needle Penetration Tester

Functional Features

Display accuracy: The measured cone penetration value can be directly read through the LCD screen, which is intuitive and accurate (up to one percent).

Structure: The flexible and lightweight cone adjustment lifting mechanism can be roughly or finely adjusted, with digital setting/control of timing time. The timing electromagnetic mechanism locks the falling cone and cone rod, and the steel structure work tool has a flexible working stroke; Equipped with a full cone.

● It has the functions of coarse and fine adjustment of the lifting frame, easy adjustment, and accurate needle alignment.

Equipped with a tamper, a constant temperature bath, and automatic temperature control for the water bath, the instrument is versatile and cost-effective.
