Used to determine grade of bitumen. The penetration tests determine
consistency of bitumen for the purpose of grading..
Bitumen-Asphalt Testing Lab equipment manufacturers,exporters and Bitumen-Asphalt Testing Lab suppliers Depth in units 1/10
of millimeter to which a standard needle having a standard weight will
penetrate vertically in a duration of five seconds at a temperature of
25ºC determines penetration for gradation.

Specifications
: 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 & 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
sub-divisions and the needle pointer against figures makes easy
reading. Supplied with bitumen penetration needle, ring weight one each
50 gms, and two sample container.
Accessories : Penetration cone for empirical estimation of penetration of lubricating grease, petroleum jelly etc.
Automatic Standard Penetrometer :
Same
as above but supplied with transistorized timer and Electro magnet
incorporated in the clutch mechanism to accurately control penetration
time to exact five seconds.
