  • The fundamental conductivity and resistivity of water

    Pure water has a very low. but not quite zero, electrical conductivity. This conductivity provides a probe into fundamental properties of water, including the electrochemical mobility of the hydrogen and hydroxide ions. Deviation from this value is a measure of trace ionic impurities. Ultrapure water (UPW). with impurities at or below the sub-parts-per-billion range, is used extensively in many ...

  • Compare popular resistivity meters with FlashRES

    Although most resistivity meters nowadays can collect resistivity, IP and SP data and most of these systems are multi-channal resistivity meters, there is still a technical gap between traditional and next generation resistivity meters. FlashRES has six to 8 times more channel than traditional system, this means larger data quantity, which could help the resistivity inversion image ...

  • A new categorisation method of resistivity instruments

    This paper presents a new categorisation method of resistivity instrument: Conventional arrays-oriented resistivity instruments (conventional instruments) vs. Comprehensive array-oriented resistivity instruments (comprehensive instruments). The conventional instruments were ...

  • Sorption and resistant desorption of Atrazine in typical Chinese soils

    Atrazine is one of the most commonly used herbicides and is produced and used in large quantity worldwide. In the present study, the sorption and desorption of atrazine in five typical Chinese soils were examined. The sorption of atrazine followed the conventional linear isotherm reasonably well, indicating that sorption was driven largely by hydrophobic partitioning into soil organic matter. ...

  • Superior abrasion resistance demanded by sump cleaning

    Acquired by a open pit mining company located in the Minas Gerais province for a slurry application (up to 60% solids concentration) in a sedimentation sump, the Grindex Bravo 60 pump lived up to its name, proving it's the ideal solution for a wide range of similar installations. In this case ...

  • New and diverse sources of multiple disease resistance in Wheat

    Tan spot (caused by Pyrenophora tritici-repentis) and Stagonospora nodorum blotch (SNB), (caused by Phaeosphaeria nodorum) are destructive diseases of wheat (Triticum aestivum L.). The majority of currently grown wheat varieties are susceptible to both diseases, presumably because of high pathogenic variability occurring in these fungi or narrow genetic background for resistance in wheat ...

  • Puraflex Data sheet

    The Puraflex product data sheet.  The data sheet gives information regarding the various different physical properties of the material such as tensile strength, hydrostatic resistance, and coefficient of thermal expansion as well as the durability properties such as UV resistance, oxidative induction time, and temperature range.  Information is also given with respect to the various ...

  • Hydrogeophysics: VLF / SuperSting multi-electrode electrical resistivity surveys

    PROJECT: VLF and multi-electrode SuperSting surveys at a large tract of farmland LOCATION: California (specific location is Confidential, per client's request) PROJECT DESCRIPTION: Designed and performed a reconnaissance VLF survey and subsequent exploratory SuperSting 84-electrode geophysical surveys across a suspected water-bearing trend occurring ...

  • Pullout Resistance of Steel Geogrids with Weathered Clay as Backfill Material

    The pullout resistance of welded steel geogrid reinforcement embedded in poor-quality, cohesive-frictional backfill material such as weathered clay was investigated. Laboratory pullout tests were conducted on various reinforcement sizes, mesh geometry, and compaction conditions of the backfill material. Field pullout tests were also conducted to investigate the pullout resistance of ...

  • Time-lapse resistivity investigations for imaging saltwater transport in glaciofluvial deposits

    Abstract  Five intersecting resistivity sections have been measured in glaciofluvial deposits hosting an aquifer of regional importance situated along a heavy traffic highway in Sweden. The winter salt spreading has caused a regular salinity increase through the years. For imaging the transport of saltwater in the aquifer, the sections were measured exactly in the same location before and ...


  • Case Study - Panama Canal: Boat Towed 3D Resistivity Surveys

    77 km Long 3D Canal Floor Sediment/Rock Study for Dredging Estimates Boat towed streaming dipole-dipole resistivity data were successfully used to estimate geotechnical properties of the canal floor in order to reduce dredging costs for an ongoing Panama Canal expansion program. Site:  The 77-km long Panama Canal with 773 line-km of resistivity data collected at 25 m transect spacing ...

  • Full waveform data display

    FlashRES resistivity meter displays full current and voltage data when the system is collecting these data. The real time read out of the data effectively helps operator to monitor the data quality. In case the data quality Q factor drops in value, the operator can pause the data collection process and check the background, contact and instrument noise. Displa full waveforms thus protect ...

  • Ultrapure water – The standard for resistivity measurements of Ultrapure water - Case Study

    Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, ...

  • IP data collection

    FlashRES resistivity meter collects 4*N voltages for each AB current injection. When operator sets the instrument collect IP data, the system will default the on time equals to the off time. ZZ finds sometime operators need customise their IP windows, thus FlashRES records all the data and this enables operators to form their own IP windows data with their own window size criteria. ...
