  • Surcis launch a new respirometer of double reactor with automatic pH and temperature control

    This development has been approached to attend the current increasing demand of this type of respirometry analyzers in the market, where the benefit to get the two reactors permits the performance of two respirometric tests simultaneously and their comparison for assessment purposes. Surcis had already developed the model BM-EVO2 and the main difference with the BM-Advance is that this new ...

  • ASTM D1287 - 11 standard test method for ph of engine coolants and antirusts

    pH is a measure of the hydrogen ion concentration and indicates whether an engine coolant, antirust, or a solution of these compounds is acidic, alkaline, or neutral. The pH range includes values from 0 to 14. Values from 0 to 7 represent the acidic half of the scale. Values from 7 to 14 represent the alkaline or basic half of the scale. The pH value 7 is considered neutral, ...

  • ASTM D1293 - 12 Standard Test Methods for pH of Water

    The pH of water is a critical parameter affecting the solubility of trace minerals, the ability of the water to form scale or to cause metallic corrosion, and the suitability of the water to sustain living organisms. It is a defined scale, based on a system of buffer solutions with assigned values. In pure water at 25°C, pH 7.0 is the neutral point, but this varies with temperature and the ...
