The purity of water is an important aspect in many industries and sectors, such as pharmaceutical, food and beverage, life science, power plants, and many others which require pure water for day-to-day laboratory testing and activities. The measurement of pH in pure water samples is critical due to its low conductivity, fluctuations in liquid junction potential of electrode, and also lack of sensitivity of glass membrane. Using specialist laboratory pH sensors eases pH measurements in such low ionic water samples. Watch this video to see how the METTLER TOLEDO InLab Pure and InLab Pure Pro-ISM electrodes are specially formulated for pH testing in pure water applications.
