A 4t industrial boiler hot selling water testing methods) and storage of water samples taken 1, depending on the volume of water analysis items, only a simple analysis of water samples is generally 500 to 1000 ml. 2, the sample container should be filled with water using a rigid glass or plastic bottle. Never use of wood, paper balls, metal plugs and maize. 3, sampling Note Samples should be slowly into the bottle, it can not produce water rippling. When the water sample into the bottle 10 ml shall be left void, or to prevent the water temperature changes, the cork pushed open. When averaged water sample must be taken at the same time under the same conditions. Determination of the hydrogen ion concentration in water (B) PH value of which depends mainly on the carbon dioxide, bicarbonate ion content of between opposing sulfate ions, but also somewhat affected by other ions. Whichever it is usually expressed negative numbers. Symbol "PH". PH = log [H +] measured PH value method has potential method and colorimetry, only the chapter describes the more common potential method. PH value of measured potential method, the potential difference between the solution is indicated in the measurement and reference electrodes difference generated. The potential of the reference electrode is constant, the potential of the indicator electrode with different PH value of the solution is changed. Thus the electromotive force consisting of a battery can be measured accurately with the compensation method. Using PH PH meter can be directly measured value of the solution. The procedures for measuring PH meter may be used, accuracy of 0.01.
