  • 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 ...

  • Battery-powered chlorine monitor

    Athenea is the new chlorine monitoring system for potable water networks from Halma Water Management (HWM). It is an autonomous, battery-powered chlorine analyser that provides continuous monitoring of concentration levels and transmits data automatically via cellular telemetry. This greatly reduces the need for time-consuming on-site ‘spot" testing, and obviously allows for much more ...

  • METTLER TOLEDO Produces Hints and Tips Guide on Improving DO and pH Measurement Accuracy

    Process analytics using in-line sensors plays a major role in monitoring manufacturing to ensure the required process conditions are always being met. Obviously, reliability of the data from sensors correlates with sensor measurement accuracy, but accuracy is not solely dependent on the use of high quality sensors. Sensor maintenance and calibration procedures significantly influence a ...
