Ground Conductivity Meters
The EM38 Series: Industry's Most Trusted EM Tools
From precision agriculture to environmental site assessment, the EM38 series delivers unmatched subsurface data without disturbing the surface.
The Global Standard for Shallow Subsurface Mapping
The industry's most trusted electromagnetic induction tool for rapid, non-invasive characterization of the near-surface up to 1.5 meters deep. Simultaneously measures apparent conductivity and magnetic susceptibility at two distinct depths — no ground contact required.
- Dual depth exploration (0.5 m & 1.0 m coils)
- Integrated Bluetooth® to Mesa field tablet
- Enhanced temperature compensation — zero drift
- Operates from -40°C to +50°C
Depth
Up to 1.5 m
Frequency
14.5 kHz
Coils
2 receiver coils
Next-Generation Four-Coil Profiling
Four receiver coils provide simultaneous conductivity & susceptibility at four distinct depths in a single pass — delivering a high-resolution profile of the soil column for complex environmental assessments.
- 4× depth resolution vs. MK2
- High-efficiency Mesa-compatible workflow
- Non-invasive — no ground contact
- Integrated GPS/GNSS georeferencing

Wide-Area Terrain Conductivity Mapping to 6 m
A frequency-domain electromagnetic terrain conductivity meter available with a 2 m (short) or 3.66 m (12 ft, standard) fixed boom, providing a nominal exploration depth of ~3–6 m (vertical dipole) or ~1.5–3 m (horizontal dipole) — without electrodes or ground contact. Simultaneously measures apparent conductivity and magnetic susceptibility with an integrated data logger and real-time LCD survey display for in-field quality control.
- Available in 2 m or 3.66 m (12 ft) boom configurations
- Integrated data logger with real-time LCD survey map
- Automatic drift & tilt compensation
- Conductivity range 1–1000 mS/m, ±5% accuracy
Depth
Up to ~6 m
Frequency
9.8 kHz
Coils
Tx + 1 Rx
