Standard Penetrometer

Product Details :

Standard Penetrometer

Used to determine grade of bitumen. The Standard Penetrometer tests determine consistency of bitumen for the purpose of grading. Depth in units 1/10 of millimeter to which a standard needle having a standard weight 0 will penetrate vertically in a duration of five seconds at a temperature of 25 C determines penetration for gradation.

Components: It consists of a vertical pillar mounted on a base provided with leveling screws. The head, together with dial plunger rod and cone (or needle) slides on a pillar and can be clamped at any desired height. A rack and pinion and pointer assemble provides fine adjustment of needle or cone tip to sample. It incorporates a clutch mechanism which makes reading of penetration and subsequent resetting a simple and accurate operation. The dial is graduated in 400 1/10 and the millimeter subdivisions and the needle pointer against figures makes easy reading. Supplied with a bitumen penetration needle, ring weight one each 50gms and two sample containers.

Accessories: Penetration cone for empirical estimation of penetration of lubricating grease, petroleum jelly etc.
