Advanced TechnocracyInc. is Manufacturer, Exporter & Supplier of STANDARD PENTROMETER
Used to determine grade of bitumen. The penetration tests determine consistency of bitumen for the purpose of grading. Depth in units 1/10 of milli meter to which a standard needle having a standard weight will penetrate vertically in a duration of five seconds at a temperature of 25deg C determines penetration for gradation.
Specifications: It consists of a vertical pillar mounted on a base provided with levelling 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 milli meter 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.
