Electric Plastic Liquid Limit Test Cone Penetrometer

Description

Introduction Electric Plastic Liquid Limit Test Cone Penetrometer

The Electric Plastic Liquid Limit Test Cone Penetrometer represents a significant advancement in soil consistency measurement. Laboratories that perform Atterberg limit determinations depend on accurate data to classify fine-grained soils and make safe engineering decisions. Traditional manual methods introduce human error and slow down workflow. This electric cone penetrometer eliminates those problems by automating the penetration measurement and digitally recording depth readings in real time.

Key Features Electric Plastic Liquid Limit Test Cone Penetrometer

• Digital LED/LCD display reads penetration depth to 0.01 mm resolution — eliminates manual gauge reading errors
• Electric motorised cone release — ensures consistent 5-second cone drop every test, removing operator variability
• 80 g stainless-steel 30° cone — machined to BS 1377 specification for internationally recognised results
• Automatic depth lock — freezes the digital readout the instant the cone stops, giving stable and repeatable readings
• Adjustable cone height — the screw-lift platform lets operators position the soil cup precisely without guesswork
• Compact, stable cast-iron base — resists vibration and keeps the instrument level during measurement
• Simple two-button operation — minimal training requirement suits technicians at all experience levels
• Dual power supply (AC mains and battery option) — supports both laboratory bench use and field site testing
• Corrosion-resistant stainless-steel contact parts — extends service life in humid tropical laboratory environments like Bangladesh Electric Plastic Liquid Limit Test Cone Penetrometer

 

Applications Electric Plastic Liquid Limit Test Cone Penetrometer

• Liquid limit determination of fine-grained cohesive soils (clay, silt, and silty clay)
• Atterberg limit testing for soil classification in geotechnical investigation reports
• Subgrade soil assessment for road, highway, and airport runway design
• Foundation soil evaluation for building, bridge, and embankment projects
• Quality control testing of soil fill materials on construction sites
• Slope stability analysis — understanding plasticity index from liquid and plastic limit data
• Compaction control — linking soil consistency limits to optimum moisture content
• Environmental site assessments — characterising contaminated or expansive soils
• Educational laboratory exercises for civil and geotechnical engineering students Electric Plastic Liquid Limit Test Cone Penetrometer

 

Frequently Asked Questions (FAQ) Electric Plastic Liquid Limit Test Cone Penetrometer

Q1: Does this cone penetrometer comply with BS 1377: Yes. The instrument uses an 80 g, 30° stainless-steel cone and a motorised 5-second drop — both requirements of BS 1377 Part 2. The digital display reads to 0.01 mm, which exceeds the standard resolution requirement.

Q2: Can I also determine the plastic limit with this machine: The machine measures the liquid limit directly. Engineers calculate the plastic limit separately using the thread-rolling method and derive the plasticity index from the difference. ASTZ BD supplies the thread-rolling accessories as an add-on if you need them. Electric Plastic Liquid Limit Test Cone Penetrometer

Q3: How do I calibrate the digital display; Turn the instrument on and lower the cone to touch the reference flat plate supplied in the accessory kit. Press the zero button on the control panel. The display resets to 0.00 mm. Repeat this step at the start of every testing session.

Q4: Does the machine work with Bangladesh power supply: Yes. The instrument operates on 220 V / 50 Hz, which matches the standard Bangladesh mains supply. A two-pin power cable comes in the box. The optional battery module supports field work away from a power outlet.

Q5: What is the warranty period: ASTZ BD provides a one-year warranty covering manufacturing defects. The warranty covers the electronic display unit, motorised release mechanism, and frame. Normal wear items such as the cone tip are consumables and are not covered under warranty.

Q6: How long does delivery take across Bangladesh: ASTZ BD dispatches in-stock units within 1–2 working days of order confirmation. Dhaka metro deliveries take 1 day; other districts take 2–4 days via courier. ASTZ BD messages the tracking number to your phone as soon as the courier collects the parcel.
