PROCTOR NEEDLES.

PROCTOR NEEDLES.

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

PROCTOR NEEDLES - SPRING TYPE.
  • Order Code: AIC-PN-SP.
  • Add To Enquiry Box



Consists of a needle attached to a spring loaded plunger, the stem of which is calibrated to read 0 to 40 kg in 1 kg Division. Long stem is graduated at every 12.5 mm to read depth of penetration and for use with needles of larger areas. The small penetration is also graduated in 12.5 mm division and used with needle of small areas. Needle points one each of 0.25, 0.5, 1.0, 1.5, 2.0, 3.5 and 6.0 cm. and one Tommy pin is supplied with the instrument in a nice carrying wooden case.

PROCTOR NEEDLES - HYDRAULIC TYPE.
  • Order Code: AIC-PN-HY.
  • Add To Enquiry Box



This is identical to spring type Proctor Needle, except that the penetration pressure on the needle is conveyed through a hydraulic system to a hydraulic pressure gauge. This system permits a great control over rate of penetration because of better visibility of load indication. Comprises hydraulic proctor needle system complete with a pressure gauge fixed at easily readable angle reading 0 70 Kg x 2 kg. A set of needle points consisting one each of 0.25, 0.5, 1.0, 1.5, 2.0, 3.5 and 6 cm2. and one Tommy pin.

Graduation at every 12.5 mm to indicate depth of penetration are marked on longer stem for use with needles of larger areas. Smaller stem is also graduated at every 12.5 mm and is used with needles of smaller areas. Complete as above in a wooden carrying case.
