  • Conductivity Temperature Correction (.pdf)
    Temperature correction procedure for Denver Instrument conductivity meters.
  • Circuit Board Cleanliness Testing
    Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. This application bulletin explains how a simple "on line" test for the relative measurement of ionic contamination using a conductivity meter has been developed to determine
  • Medium Purity Condensate Monitoring
    with a standard conductivity meter. In the case of large boilers, such as those used to generate electricity, the allowable level of solids is in the low parts-per-million range. The conductivity caused by the dissolved solids is often masked by the larger conductivities of water treatment chemicals
  • A Microfluidic System for Biological Particle Enrichment Using Contactless Dielectrophoresis
    of the buffer was. 130 mS/cm and was measured with a Mettler-Toledo SevenGo. pro conductivity meter (Mettler-Toledo, Inc., Columbus,. OH) to ensure that its conductivity was 130 ms/cm. These cells were observed to be spherical, with a diameter. of w13 mm when in suspension. Carboxylate-modified polystyrene
  • MSilica Nanoparticles Treated by Cold Atmospheric-Pressure Plasmas Improve the Dielectric Performance of Organic-Inorganic Nanocomposites
    . diameter beads that were carboxylate-modified polystyrene. microspheres (Invitrogen Molecular Probes, Eugene, OR,. USA) suspended in deionized water. The electrical conductivity. of the deionized water was determined using a MettlerToledo. SevenGo Pro conductivity meter (Mettler-Toledo,. Columbus, OH
  • Bromide Analysis in Water
    The following analysis is valid for bromide levels as low as 0.5 ppm. Check the deionized water used in reagent preparation. The specific conductivity should be no greater than 2.0 uSCM-1 (5 Mohms). Sample solutions should be free of iodide and sulfide ions. Equipment: Meter: pH/Millivolt meter
  • The Challenges of Measuring Flare Gas
    for this associated gas from day 1. This of course requires a flow meter calibrated to measure the flow rate of the flare gas. Virtually all current flow measurement technology requires a known composition for calibration. This presents a "chicken or egg" problem, since the composition may not be known
