short info

Proctor needles are used for quick evaluation of maximum soil density in the field. Standard Compaction curves showing moisture contents versus densities are drawn in laboratory using standard compaction method and penetration of the proctor needles are correlated. Proctor needles are also known as Proctor Penetrometers.

OVERVIEW

Designed for use in the field for controlling soil compaction by initial calibration from laboratory tests for moisture density relationship. The instrument consists of a barrel housing a spring.

A piston compresses the spring and the piston rod is calibrated upto 40 kg in 1 kg divisions. Two penetration stems which can be attached to the other end of the spring barrel, one at a time, to suit the needle point being used, are graduated in 1.25 cm divisions.

Supplied with eight needles of 6.0, 5.0, 3.0, 2.0, 1.5, 1.0, 0.5 and 0.25 cm² area.

Complete in a wooden box.



SPECIFICATIONS

Technical Specification:-

  • Consist of needle attached to a spring loaded plunger.
  • The stem of which is calibrated to read 0 to 40 kgs in 1 kg division.
  • Long stem is graduated at every 12.5mm to read depth of penetration and for use with needles of larger areas.
  • The small penetration steam is also graduated in 12.5mm division and is used with needles of smaller areas.
  • Needle points one each of 0.25, 0.5, 1.0,1.5,2.0, 3.5, and 6.0 sq.cm.
