One Strip - One Dip - One Match Only one color to match for a clear and positive result. Hydrion pH papers provide a simple fast and reliable method of pH measurement. Just dip paper and match to the color chart. Tap, pond and rain water should be tested using Hydrion Lo-Buff Lo Ion pH Test Paper. pH Level Testing Maintaining and controlling proper pH levels is essential to many agricultural, industrial and environmental processes. In agriculture, proper pH of the soil ensures good crop growth. For drinking water, processing plants have to control pH in order to produce safe drinking water. Environmentally, pH monitoring and control are critical to prevent damage or deterioration of the quality of all plant, animal and human life. pH Level Testing pH is a numeric scale used to express a solution’s acidity or alkalinity. Acidity or alkalinity refer to a solution’s concentration of hydrogen ions. The greater the concentration of hydrogen ions, the more acidic the solution. The fewer hydrogen ions and a solution is considered alkaline.The pH scale ranges from 0 to 14. Seven is the midpoint at which a solution (such as distilled water) is neither acid oralkaline. A pH lower than seven indicates more acidic solutions like vinegar (3.0 pH), sulfuric acid (1.2 pH) or orange juice (3.7 pH). pH values higher than 7 represent alkaline or basic solutions such as sodium hydroxide (pH 13), ammonia base household cleaners (pH 12), and potassium hydroxide (pH 14). Ways to Measure pH The first step in controlling pH is measuring it. pH can be measured by various methods including pH paper, digital readout pocket testers, portable and bench top meters. pH paper is an inexpensive and quick way to check pH. Strips of paper are impregnated with a chemical indicator. This indicator, when immersed in a sample liquid, turns the paper test strip a specific color. The pH of the sample liquid is determined by visually comparing the color of the test strip to a standard chart. Pocket and Bench pH Testers An alternative to pH paper is the pocket tester. Convenient and easy to carry, these testers are ideal for field use. pH tests can be made quickly without having to take a sample back to the laboratory. Pocket testers provide enough accuracy for general applications and are relatively inexpensive. When more accuracy is required, portable meters are a good choice. Most portable meters are larger in size than pocket pH testers. They use a wide variety of replaceable pH electrodes for individual applications and conditions. Bench top meters are found mainly in testing or research laboratories. They are generally more expensive but offer increased accuracy and more testing options. |
