Detailed Product Description

DZD-8 Multi-function Full Wave DC Electron Meter Environmental site assessments demand defensible data. The DZD-8
Multi-function Full Wave DC Electron Meter delivers repeatable
resistivity and IP measurements that stand up to regulatory review.
Whether you are mapping a contaminant plume, locating a landfill
boundary, or imaging a saltwater intrusion, this instrument
provides the evidence you need. Full Waveform Recording Technology Traditional meters average signals, hiding transient noise from
nearby pumps, traffic, or telluric currents. The DZD-8 records 1KHz
waveforms of both current and potential. You can visually inspect
each measurement. If noise is present, you see it. You can also
recalculate polarizability using different delay times - a critical
feature when the secondary field from clay or organic contamination
is weak. Accuracy Specifications Voltage resolution 5nV, accuracy ≤0.1% for signals >1mV. Current
resolution 10nA. Apparent polarizability error ≤±0.2%. These
specifications exceed typical environmental requirements, providing
verifiable data quality for regulatory compliance. Measurement Parameters
All parameters are measured from a single measurement sequence. Field Workflow for Site Assessment
Advanced Survey Capabilities Rolling measurement extends profiles without moving all electrodes.
After completing one section, the system prompts you to move a
subset of cables, enabling efficient surveys of hundreds of meters
with a single cable set - ideal for long pipelines or shoreline
assessments. 3D ERT for detailed source zone imaging supports S, U, W, or Wang
cable layouts with up to 60 or more electrodes depending on
configuration. The 3D preprocessor allows data editing, bad
electrode deletion, and export to inversion software for final 3D
modeling in GIS or CAD. Data Security and Chain of Custody All raw waveforms are saved on the internal SD card (16G to 64G
optional). USB transfer is simple - the instrument appears as a
drive. No proprietary formats requiring expensive software. The
provided analysis software exports to ASCII, Res2Dinv, Res3Dinv,
and Surfer formats, maintaining raw files as audit trail. Rugged Field Performance IP67 waterproof - can be hosed off after dirty surveys. Operating
temperature range -20°C to +60°C. The 6.4 inch high-brightness LCD
remains readable in direct sunlight. The enclosure withstands
vibration from trucks and generators. Power Management Internal 16.8V 12.5Ah battery provides 20 hours of operation. For
multi-day assessments, connect a 12V external battery via the
charge port. The instrument displays remaining charge as a
percentage with orange screen warning below 15%. Transmitter Performance Maximum 1400V and 6A, 7500W output. In urban settings with low
ground resistance, only 50-100V may be needed. For resistive dry
sand or gravel, higher voltage pushes current through. Pulse width
adjustable from 1 to 64 seconds - longer pulses improve
signal-to-noise for deep or noisy sites. Field Troubleshooting Guide
The manual includes a four-resistor test (1kΩ, 100Ω, 1kΩ in series)
to verify instrument channels before each major project. Software Capabilities The "Multifunctional DC analysis software" provides:
No subscription fees - purchase once, use forever. Technical Specifications
