Pocket penetrometer: SpecificationsAs per soil clssification catalogs Wykeham Farrance / CONTROLS (STANDARD POCKET PENETROMETERS16-T0171Pocket penetrometerrange 0-5 kgf/cm2Designed for making field classificationof cohesive soils in terms of consistency,shear strength and approximate unconfinedcompressive strength.BDimensions:20 mm dia. x 173 mm lengthA Weight approx.: 0.5 kg16-T0163Heavy duty pocket penetrometerUsed to obtain quickly and easily an approximatemeasure of the shear strength ofcohesive and semicohesive soils. The specialfeature of this model is the design of thepenetration rod, which allows a relativelydeep penetration into the soil (up to 6 cm)thus reducing errors and uncertainties typicalof shallow measures, which are oftenaffected by remoulding, drying, etc.Threedifferent sizes of penetration tips are available:the small one for hard soils, the mediumone for soft and medium soil, and the largeone for soft soil.SpecificationsAll stainless steel construction tip diameters(interchangeable): 4.5 mm forvery hard soil; 6.35 mm for medium andsoft soil; 8.98 for soft soil.Supplied complete with plastic case.Measuring range: 0 to 10 kgf/cm2BDimensions (assembled): 210 mmlength x 20 mm dia. approx.A Weight approx.: 0.5 kg
