Liquid Limit Penetrometers
The cone penetrometer apparatus is used to determine the moisture content at which clay soils pass from a plastic to a liquid state and it is used also for the determination of undrained shear strength (CEN ISO/TS 17892-12).
Two versions available: the standard 22-T0029/D and the semi-automatic 22-T0029/E.
(Conforming to NZS 4402.2.5:1986)
The penetrometer has a cast iron base with leveling screws, digital penetration measurement gauge 0.01 mm precision, release button and automatic zeroing.
It is provided with lead screw gear arrangement, Leveling screws, Spirit level.
The head can be clamped at any desired height. A rack and pinion and pointer assemble provides fine adjustment of the cone tip to sample. It incorporates a clutch mechanism which makes reading of penetration and subsequent resetting a simple and accurate operation.
The semi-automatic model is complete with automatic controller, which automatically releases the plunger by a magnetic device, complete with micrometer vertical adjustment and adjustable electronic timer of the fall time. The electronic timer allows the user to set up and read the fall time of the needle during testing.
Penetration cones, gauges and sample cups are purchased separately.
Common sizes we usually have in stock:
22-T0029/1: Penetration test cone 30° angle
22-T0029/2: Cone test gauge to check the condition of the cone
