Used to determine the consistency of a bituminous sample under fixed conditions of load, time and temperature. The penetration is expressed in distance of tenths of millimeters vertically penetrated by a standard needle Basically structured as mod.
Magnetic controller device with electronic digital programmable timer that automatically releases the plunger head and ensures free falling of the needle during the 5-seconds test.
Power: 220-240 V 1ph 50 Hz 200 W.
Dimensions: 220x280x410 mm.
Weight: 15 Kg.
The penetrometer is basically a device that is used to measure the depth of the soil. The Semi-Automatic Penetrometer measures the level of moisture content in clay soils during the transition from plastic to liquid state.
It contains leveling screws, special soil penetrometer, digital penetration measurement indicator with 0.01 mm precision and release button. Thanks to its steel base and automatic zeroing feature, it provides significant convenience to those who perform the measurement during the measurement.
This device, which measures the moisture in the soil with a spirit level, can be used easily thanks to its automatic timer unit. At the same time, this unit specifically determines the time to release the needle plunger.
Along with the Semi-Automatic Penetrometer, there are also 30 degrees Penetrating cone, timer unit, 55×35 mm diameter aluminum cups.
What Does a Semi-Automatic Penetrometer Do?
The Semi-Automatic Penetrometer determines the moisture content of soils containing different amounts of clay from the plastic state to the liquid state, and also determines the undrained shear strength.
The measurement time has a free fall time of 5 seconds as standard, which can be extended up to 99 seconds in special experiments. Semi-Automatic Penetration Device provides easy detection and recording of data thanks to its measurement indicator. Its digital display can even read clay soil with a resolution of 0.01.
This device, which has a very simple working principle, measures when it is adjusted by freely penetrating the sample with its needle.
