Liquid Limit Penetrometers
Product Code : EL-STLE-10382
Quick Answer: The Liquid Limit Penetrometer is a cone penetrometer apparatus used to determine the moisture content at which clay soils pass from a plastic to a liquid state, and to determine undrained shear strength. It has a cast iron base with levelling screws, a digital penetration measurement gauge with 0.01mm precision, an automatic zeroing electronic release mechanism, and a micrometer vertical adjustment device, and the semi-automatic model features an automatic controller that releases the plunger via a magnetic device along with an adjustable electronic timer for the fall time.
Key Features:
Cast iron base with leveling feet
Digital penetration measurement gauge 0.01 mm precision
Micrometer vertical adjustment device
Automatic zeroing
Electronic release mechanism
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. The penetrometer has a cast iron base with leveling screws, digital penetration measurement gauge 0.01 mm precision, release button and automatic zeroing, and it is provided with a lead screw gear arrangement, leveling screws, and spirit level.
It incorporates a clutch mechanism which makes reading of penetration and subsequent resetting a simple and accurate operation, and the head can be clamped at any desired height. A rack and pinion and pointer assembly provides fine adjustment of the cone tip to the sample.
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 and sample cups have to be ordered separately.
