You\u2019ve finally bought a professional pH meter and shelled out a pretty penny for it, but don\u2019t think the hard work is over\u2014now it\u2019s time to make the most of your purchase.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

We know how important this measurement is throughout the entire brewing process, so it is essential that it be accurate!
So having a good pH meter isn’t enough\u2014you also need to know how to use it properly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Buying a good pH meter isn\u2019t enough\u2014even though it\u2019s a crucial step\u2014to ensure accurate measurements, since low-quality pH meters, even when calibrated, can produce completely inaccurate readings.<\/p>

Once you\u2019ve made a good purchase, it\u2019s important to ensure that your new instrument lasts as long as possible, and to do that, you need to perform proper maintenance on a regular basis.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Let\u2019s start right away with a topic that may seem obvious but is still seriously underestimated: how to take an accurate measurement with our pH meter. First of all, even though our SUPER pH meter is equipped with ATC (automatic temperature compensation), it\u2019s absolutely essential to know that to take an accurate measurement, you must do so at the same calibration temperature of 20\u201325\u00b0C. <\/p>

But if I bought a self-calibrating pH meter, why can\u2019t I put the probe in the boiling wort?<\/em><\/p>

  1. The compensation accounts for the temperature-dependent variation in the probe\u2019s measurement, not for changes in the measured liquid (the dissociation of H+ ions will differ at 25\u00b0C compared to 80\u00b0C).<\/li>
  2. Even though the probe is labeled as heat-resistant up to 100\u00b0C, the hotter you make it, the shorter its lifespan will be!<\/li><\/ol>

    Another very important point is that the pH meter MUST be properly calibrated.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Here are the techniques and tips that I can tell you apply to all instruments:<\/p>\n

      \n
    1. Always choose COLORED calibration solutions; this will allow you to detect changes in the solution\u2019s pH, as the color is specifically designed to indicate whether microbiological changes have altered the pH of your buffer solution. Additionally, with colored solutions, you\u2019ll make fewer mistakes. \n<\/li>\n
    2. Never dip the pH meter probe directly into the original bottle of pH solution, as this could contaminate it and force you to buy a whole new bottle\n<\/li>\n
    3. Make a small jar with a little solution and replace it often\n<\/li>\n
    4. Between measurements, rinse the electrode with drinking water (NOT deionized water) and dry it with TOILET PAPER (which is different from a large roll of paper towels) or with a special antistatic laboratory wipe.<\/li>\n<\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
