Liquid Limit Device

Used to evaluate the relationship between the moisture percentage of a soil sample and the number of blows required to close a groove made into the soil; and therefore to determine when a clay soil changes from a plastic to a liquid state.

The device is available in two models:

• Hand operated,

• Motor operated at 120 drops/min speed, ensuring better uniformity and accuracy

Comprises a removable brass cup, adjustable crank and cam mechanism, blow counter and base.

Supplied with Brass grooving tool.

Resilience Tester is used for measuring the resilience of liquid limit device bases. Resilience Tester consists of a clear acrylic plastic tube, steel ball and a small bar magnet. Resilience Tester should be ordered separately.

Linear Shrinkage Mould

Mould to produce a specimen of 140 mmlong x 12,5 mm radius.

This test covers the determination of linear shrinkage of soils and indicates the plastic properties of soils with a low clay content.

Shrinkage Limit Test Set

Cone Penetrometer

Semi-Automatic Digital 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.

It is provided with lead screw gear arrangement, Leveling screws, and 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.

Semi-Automatic Digital Penetrometer for Liquid Limit 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 penetrometer is equipped with a digital timer, which can be set to the standard 5 second free-fall time or to some other setting for customized tests. When engaged the timer will allow the needle to free fall into the sample for the specific time interval and then lock the needle from advancing while providing a direct reading of the test results.

320 g weight should be added to the 30° angle cone to get a total weight of 400 g for the shear strength test.

The electronic timer allows the user to set up and read the fall time of the needle during testing.

Semi-Automatic Penetrometer for Liquid Limit supplied complete with

• Automatic Penetration Timer Unit,
• 30° Penetration Cone
• Sample Cups, 3 pcs. Aluminum, Ø55 mm x35 mm.

Mirror is available for easy cone height adjustment and should be ordered separately.

Hydrometer Test Set

This equipment is used to determine the quantitative size distribution of very fine particle in soils such as clay and silt.

Two models are available.

HR-S6450 Hydrometer Test Set is Supplied with Hydrometer Water Bath, Circulation Pump, Heater, High Speed Stirrer, 6 x 1000 ml Sedimentation Cylinder, 0,995 to 1,038 g/ml range 151 H Hydrometer, 1 kg Sodium Hexametaphosphate and 600 ml Beaker.

HR-S6460 Digital Hydrometer Test Set is Supplied with Digital Hydrometer Water Bath, Circulation Pump, Heater, High Speed Stirrer, 6 x 1000 ml Sedimentation Cylinder, 0,995 to 1,038 g/ml range 151 H Hydrometer, 1 kg Sodium Hexametaphosphate and 600 ml Beaker.

The Hydrometer Water Bath, circulation unit, ambient to 35°C working temperature, 50 L capacity tank with 8 pieces Sedimentation cylinder capacity. The Water Bath is available in two models one with Analogue and the other one with Digital Indicator.

High Speed Stirrer operates at over 10,000 rpm, includes dispersion cup, stirring paddle, automatic switch-on by positioning bowl.

-5 to 60 g/l range 152 H Hydrometer should be ordered separately.

Cooling coil and clamps should be ordered separately.

Measuring Soil Texture Test Set

Texture, or size distribution of mineral particles (or its associated pore volume), is one of the most important measures of a soil because finely divided soil particles have much greater surface area per unit mass or volume than do coarse particles. Thus, a small amount of fine clay and silt will be much more important in chemical reactions, release of nutrient elements, retention of soil moisture, etc., than a large volume of coarse gravel or sand.

Measuring Soil Texture Test Set is supplied with High Speed Stirrer,-5 to 60 g/l range 152 H Hydrometer,Bouyoucos Cylinder, 1205 ml and Stainless Steel Stirring Rod.

High Speed Stirrer operates at over 10,000 rpm, includes dispersion cup, stirring paddle, automatic switch-on by positioning bowl.

38 mm Hand Operated Hydraulic Sample Extruder

38 mm Hand Operated Hydraulic Sample Extruder with Trimming Knife, 38mm Split Former & Cutting Tool comprises a vertically mounted lever action hydraulic jack, with the body extended to form a chamber which accommodates a 38 mm diameter sample tube.

Supplied complete with Trimming Knife, 38mm Split Former, Wire Saw and 12 pieces Wire.

Soil Lathe

Designed to reduce by trimming the diameter of a soil sample unit is reaching the desired diameter size by using a wire saw.

Soil Lathe can trim and Extrude samples from 35 mm to 100 mm diameter. It should be used together with Open Wire Saw.

The lathe is hand-operated, the height is adjustable up to 230 mm.

Open Wire Saw, Wires, Trimming Knife should be ordered separately.
