Used to determine grade of bitumen. The penetration 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 will penetrate vertically in a duration of five seconds at a temperature of 25ºC determines penetration for gradation.

Salient Features:

• 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.

Features:

We provide highly efficient rapid moisture meter which is basically used for quick determination of moisture percentage of materials in powder form like Soil.

Calcium carbide when comes in contact with moisture acetylene gas in generate. This principle is used in rapid moisture meter. A weighted quantity of sample is mixed with fixed quantity of calcium carbide reagent and the whole mixture is thoroughly shaken in a vessel to which a pressure gauge is fixed. The acetylene gas produced developes pressure and pressure gauge is calibrated to read percentage moisture. The instrument indicates moisture on wet/weight basis easily convertible to dry weight basis.

The apparatus is offered in polished wooden carrying case and includes:

• Pressure vessel with clamp for sealing

Rubber sealing gasket:

• Pressure gauge in moisture content 0-25% or 0-50% on wet weight basis
• A counter poised balance to weigh the sample
• A scoop for measuring carbide reagent
• One cleaning brush
• Set of 4 steel balls and one bottle of calcium carbide (500 gm)
