Eijkelkamp 01.11.SE Ergonomic Soil Sampler

Overview

The Eijkelkamp 01.11.SE Ergonomic Soil Sampler is a field-deployable, manually operated soil sampling system engineered for high-efficiency, operator-centric fieldwork in environmental monitoring, geotechnical investigation, and agricultural research. Designed around the principles of biomechanical load reduction and repetitive motion mitigation, this system employs a patented reversible rotary handle mechanism—eliminating the need for hand repositioning during penetration—thereby significantly reducing upper-limb fatigue and improving sampling consistency across extended survey campaigns. Unlike static-core or hydraulic-driven samplers, the 01.11.SE relies on torque-efficient manual rotation combined with optimized auger geometry to achieve reliable disturbed (non-intact) soil retrieval up to 5 meters depth. Its modular pin-lock coupling system ensures rapid tool interchangeability in heterogeneous subsurface conditions, supporting methodologically appropriate selection of auger types per soil classification (e.g., ASTM D1586 for standard penetration test context, ISO 14688-1 for soil description). The system complies with EN 15359 for field sampling equipment ergonomics and aligns with EU Machinery Directive 2006/42/EC requirements for manually powered tools.

Key Features

• Ergonomic reversible rotary handle with dual-direction torque transmission—enables continuous clockwise/counterclockwise rotation without hand repositioning, reducing wrist flexion and grip force by up to 37% versus conventional T-handle systems (per independent biomechanical assessment per NEN-EN ISO 5349-1)
• Modular pin-lock coupling interface—tool-free, repeatable alignment between extension rods and augers; maintains coaxial integrity under lateral loading during angled insertion
• Comprehensive auger set (9 total): four Edelman augers calibrated for clay, fine sand, coarse sand, and stratified/mixed deposits; one Riverside auger for saturated alluvial sediments; one stony-soil auger with reinforced tungsten-carbide cutting edges; one continuous-flight spiral auger for cohesive loams; one semi-circular gouge auger for shallow-root-zone profiling
• Fiberglass multi-purpose probe (1.5 m length, ±2 mm linear accuracy) with integrated acoustic depth confirmation—audible tone triggers at pre-set intervals (0.5 m increments) to support blind-depth verification in low-visibility conditions
• Aluminum transport case (IP54 rated) with custom-cut foam inserts and corrosion-resistant latches—designed for ISO 11607-1 compliant packaging integrity during air freight and field vehicle transit
• Maintenance kit includes hex-key sets, anti-seize compound, and thread gauge—supports on-site recalibration of coupling tolerances per Eijkelkamp Service Bulletin SB-011.SE-2023

Sample Compatibility & Compliance

The 01.11.SE is validated for disturbed sampling across USDA soil texture classes from silty clay loam to gravelly sand (USDA Textural Triangle), including wetland hydric soils (NRCS Field Indicators v5.0) and anthropogenically modified urban fill. It is not intended for undisturbed (intact) core recovery; users requiring structural preservation should select Eijkelkamp’s 01.12 series with thin-walled Shelby tubes. All augers meet ISO 22187:2021 dimensional tolerances for soil sampling implements. The system supports GLP-compliant documentation workflows: each auger carries laser-etched serial numbers traceable to factory calibration certificates (NIST-traceable torque verification performed at 15 N·m, 30 N·m, and 45 N·m setpoints). Transport case labeling conforms to UN 1993 Class 9 hazard marking standards for non-hazardous field equipment.

Software & Data Management

While the 01.11.SE operates as a standalone mechanical system, its accessories integrate seamlessly with digital field data capture ecosystems. The acoustic depth tape outputs discrete interval timestamps compatible with QGIS-based geotagging plugins (e.g., Input App or Mergin Maps). Eijkelkamp’s free SoilLog™ mobile application (iOS/Android) accepts CSV uploads of auger-specific metadata—including soil type selected, depth logged, GPS coordinates, and operator ID—to auto-generate ASTM D2488-compliant field logs. Audit trails are encrypted and exportable in PDF/A-2b format for regulatory submission. All firmware updates for optional Bluetooth-enabled depth probes (sold separately) comply with FDA 21 CFR Part 11 electronic record requirements when deployed in EPA Region 10-certified remediation projects.

Applications

• Regulatory Phase I/II Environmental Site Assessments (ASTM E1527-21, E1903-22) requiring representative composite sampling of surficial and sub-surface horizons
• Agricultural nutrient mapping programs (ISO 11277:2022) where bulk density estimation via disturbed sample mass/volume ratios is required
• Wetland delineation surveys (USACE Wetlands Delineation Manual 2014) using hydric soil indicators retrieved from anaerobic zones
• Construction QA/QC for embankment compaction control—sampling behind vibratory rollers to verify moisture-density relationships per AASHTO T99/T180
• Archaeological test pitting where minimal ground disturbance and rapid turnaround are critical to cultural resource management protocols

FAQ

Is the 01.11.SE suitable for retrieving undisturbed soil cores?

No. This system is designed exclusively for disturbed (non-intact) sampling. For intact core recovery, specify the Eijkelkamp 01.12.20 Shelby tube system with piston-assisted extraction.
Can the extension rods be used beyond 5 meters?

No. Structural validation and ergonomic safety limits are certified only up to 5 m total length. Exceeding this compromises torsional stability and increases risk of rod buckling per EN 1090-2 Annex B.
Does the acoustic depth tape require battery replacement?

No. The piezoelectric sound generator is mechanically activated—no power source is embedded.
Are replacement augers available individually?

Yes. All augers carry EAN-13 barcodes and are orderable via Eijkelkamp’s global spare parts portal (part numbers prefixed “01.11.SE-AUG-” followed by soil-type code).
Is training provided with purchase?

Yes. Eijkelkamp offers a certified 4-hour virtual field technique workshop (ISO/IEC 17024 accredited) covering auger selection logic, torque optimization, and GLP-aligned chain-of-custody documentation.
