Choosing the right Static Cone Penetrometer (SCPT) can be the difference between accurate, reliable site data—or costly errors in soil evaluation. With so many models, specifications, and features available, it can be difficult to determine which penetrometer suits your project, your team, and your budget.
This buying guide will walk you through everything you need to consider before purchasing a static cone penetrometer, from essential features to optional upgrades. Whether you’re a first-time buyer or upgrading your existing equipment, these insights will help you make a smart investment.
✅ 1. Accuracy and Resolution — The Heart of the Instrument
Accuracy is the most critical feature of any soil testing device. Your penetrometer must provide precise cone resistance (qc) and sleeve friction (fs) readings.
Key Metrics to Look For:
- Resolution: At least 1/20000 A/D
- Accuracy: ±0.1% or better
- Independent channels for qc and fs (avoids signal crosstalk)
Our SCPT model meets all of these benchmarks. View full specs
🔋 2. Battery Life and Power Management
Fieldwork can stretch for hours—or days—without access to charging stations. Long battery life and low power consumption ensure uninterrupted testing.
What to Expect:
- Battery capacity ≥ 50 hours
- Rechargeable > 400 cycles
- Auto sleep/power-saving modes
- Real-time battery level indicator
🔋 Our SCPT model runs for 50+ hours on a full charge and supports extended projects without downtime.
📱 3. Data Display and Logging
Digital display is essential for real-time feedback and data integrity. Avoid devices that rely solely on manual recording.
Must-Haves:
- LCD screen with clear readability
- Multi-depth display (preferably 10 intervals)
- On-screen graph or real-time values
- Internal memory (store ≥10 full test sessions)
- Data export via USB or RS232
Our model includes a 240×128 dot matrix screen with simultaneous test result + depth display.
🧩 4. Probe Compatibility and Versatility
Different soil conditions require different probe types. A versatile penetrometer should support multiple probe heads and testing methods.
Look For:
- Double-bridge touch cone probe (standard soil)
- Pore pressure cone probe (saturated soil or embankments)
- Cross-plate probes (shear strength evaluation)
- Easy probe swap without recalibration
✅ Our penetrometer supports modular probes, giving you full flexibility across projects.
📦 5. Portability and Field Readiness
Portability matters—especially for remote sites, rugged terrains, or single-operator jobs.
Ideal Specs:
- Host weight < 1kg
- Compact design: fits into a backpack or field case
- Fully enclosed (dust/splash resistant)
- Fast boot-up and operation time
📏 Our SCPT weighs only 0.5kg, making it one of the most portable devices in its class.
💻 6. Connectivity and Software Integration
In the digital age, your device should easily connect with analysis tools and computers.
Look For:
- USB support for fast data offload
- RS232 port for older field laptops
- Compatibility with Excel, CAD, or CPT software
📊 Our model includes both USB and RS232 output, no adapter needed.
🔧 7. Build Quality and Durability
Field conditions can be harsh—your penetrometer must withstand heat, dust, vibration, and transport shock.
Features That Matter:
- Shock-resistant casing
- Industrial-grade electronics
- Stable under temperature variation
- Enclosed buttons and ports
🛠️ Our penetrometer uses a fully-sealed, heavy-duty shell designed for real-world field abuse.
💬 8. After-Sales Support and Calibration Services
No matter how good the device, you’ll eventually need:
- Troubleshooting help
- Spare parts
- Calibration guidance
- User manuals or training
Ensure the supplier offers:
- Direct technical support (e.g., via WhatsApp)
- Calibration tools or videos
- Multilingual interface (especially English + Chinese)
💬 We provide one-on-one tech support via WhatsApp, fast spare parts shipping, and training upon request.
