About This Product
A Proctor needle is a penetration probe pushed into compacted soil, and the force needed shows the resistance of the soil. In the laboratory, compaction curves of moisture content against density are drawn with equipment such as the Proctor Compaction Test Apparatus, and needle penetration is correlated with them so that the needle can be used for a quick check in the field. In the hydraulic type the force is read on a hydraulic pressure gauge. Students use it in soil mechanics and civil engineering practicals. Schools, colleges and distributors in Turkmenistan, Seychelles, New Zealand, Bosnia and Herzegovina, Libya and Latvia can source the Proctor Needles from School Lab Equipment India.
