  • Really tough: outdoor electrodes for pH, cond., O2

    HACH LANGE’s portable HQD metres and INTELLICAL electrodes measure the classic electrochemical parameters pH, conductivity and dissolved oxygen, using the drift-free optical method LDO. What makes HQD special is the newly developed INTELLICAL sensors: They store all relevant parameters and transmit them digitally to the meter. Thus making them safe from interferences and allowing for cable ...


  • ASTM D6429 - 99(2011)e1 standard guide for selecting surface geophysical methods

    This guide applies to commonly used surface geophysical methods for those applications listed in Table 1. The rating system used in Table 1 is based upon the ability of each method to produce results under average field conditions when compared to other methods applied to the same application. An “A” rating implies a preferred method and a “B” rating implies an alternate ...
