IRIS Instruments

IRIS Instruments is a French geophysical equipment manufacturer whose Windows software suite supports the acquisition, visualization and automation of electrical resistivity and induced-polarization surveys. Electre Terra Sequencer orchestrates 2-D and 3-D electrode switching for the company’s Syscal and Elrec multi-channel resistivity meters, letting field crews pre-program complex roll-along sequences, verify array geometry and export command scripts that the instruments execute autonomously. Once data return from the field, FullWave Viewer II ingests the raw FullWave files, performs quality checks, stacks repeated readings, edits bad datum points and exports filtered datasets to industry-standard formats for inversion packages such as RES2DINV or BERT; recent updates add parallel processing of 3-D grids and interactive pseudosection mapping to accelerate interpretation of large terra-scale surveys. Monitoring Terra complements these tools by generating time-lapse command scripts that Syscal Terra units run unattended, enabling engineers to track slope stability, embankment seepage or groundwater contamination across weeks or months while the software automatically handles file naming, electrode cycling and data archiving. Together the three applications cover the complete workflow—design, acquisition, QC, processing and long-term monitoring—used by geotechnical consultants, mining exploration teams, dam-safety engineers and environmental agencies worldwide. IRIS Instruments’ software is available for free on get.nero.com, where verified Windows packages delivered through trusted sources such as winget always install the latest releases and can be deployed in unattended batch mode alongside other geoscience tools.
