What you are viewing is a general tool LCD handheld pen style water PH meter. The pH of a water-based solution reflects the solution's acidity or basicity. A water PH meter is an electronic device that measures PH by detecting the PH value in the water. This pen PH meter has automatic temperature compensation function, which make the measurement accuracy of the water PH meter increased significantly. Especially measuring liquid and the space temperature difference is more outstanding. The accuracy of the water PH meter is ±0.1pH and offers more accurate test result for you. The company introduces advanced technology and imported components to greatly reduced volume, reduce the cost and keep the original fine quality. And the pen style is unique and easy to use, and you can put it into your pocket or handbag and carry it anywhere you want to go. Waterproof housing, you don't worry about it will be wet and damaged. This water PH meter is ideal for all pH testing, water purification applications, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment, wine, coffee, agriculture and so on. This water best PH meter is a great choice. Don't miss it!

    How to Use a Water PH Meter:

    Hoomool General Tool LCD Handheld Pen Style Water PH Meter

    • The pH of a water-based solution reflects the solution's acidity or basicity on a scale of 0 to 14. A pH of 7 indicates a neutral solution, a pH above 7 indicates a basic solution and a pH less than 7 indicates an acidic solution. Numerous methods exist for testing pH, including test strips and pH meters. The pH meter consists of an electronic control module and a probe. The meter actually measures the voltage across a membrane in the electrode and the control module converts this voltage to a pH value. Unfortunately, pH meters, like all scientific equipment, require periodic recalibration before they will produce reliable results. This means immersing the meter's probe into a solution of known pH and adjusting the meter to match the pH of the solution
    • Collect the sample to be analyzed in a clean, dry plastic bottle. Proper sampling technique varies by source type. If sampling a river or stream, for example, immerse the sampling bottle completely with the mouth of the bottle pointed upstream and away from the person performing the sampling. If sampling household water, allow the water to flow for 15 minutes before collecting the sample. Tightly cap the container until ready for analysis
    • Soak the pH probe in distilled water for at least 30 minutes prior to use to ensure the electrode's semipermeable membranes are thoroughly saturated
    • Prepare buffer solutions of pH 7 and pH 10 if the solution being measured is basic. Prepare buffers of pH 7 and pH 4 if the solution being analyzed is acidic
    • Follow the meter manufacturer's instructions for calibrating the meter. The exact labeling and sequence of buttons and knobs to adjust differs significantly from one manufacturer and model to the next
    • Pour a small amount of the sample being analyzed into a clean, dry plastic container. This represents the sample in which you will immerse the probe, which eliminates the risk of contaminating the primary sample. Thoroughly rinse the electrode with distilled water and blot it dry with a paper towel, then immerse it in the small sample. Allow the meter to stabilize, then record the pH value of the solution
    • Prepare the buffers and calibrate the meter again. If the results agree to within 0.1 pH units, then the measurements are reliable. If not, continue repeating the calibration and measurement until the results agree within 0.1 pH units

    How to Clean a PH Meter:

    Water PH Meter

    • A pH meter is an electronic device measures pH, which is the acidity (acids) and alkalinity (bases), of substances. pH meters loose some of their accuracy with every use and need to be calibrated on a regular basis. Along with regular calibrating, the pH meter electrode needs to be cleaned between each use to prevent contamination of the substances being measured. pH meters are usually use glass probes that are submerged into the substances being measured. The probe uses ions to attract other ions in the substances. It needs to be cleaned after every use. At all times, the glass tip of the probe is stored in a tube filled with an acidic solution around pH 3. The probe must never be stored in distilled or deionized water for long because the water will remove ions from the probe through diffusion, which can degrade the probe and its measurements
    • Gather the equipment. Most of the items are available at chemical supply stores. Procure Kimwipes, which are a special tissue specifically made for cleaning pH meters. If you cannot find Kimwipes, try to find a similar product. Distilled or deionized water will work as a general cleaner. A generally used pH-electrode cleaning solution is 0.1M of hydrochloric acid (HCl) with a pH of 1, which is used to clean the probe more thoroughly approximately once a month
    • Prepare the pH meter for measuring. Put rubber gloves on. Pour the substance being measured into one beaker. Pour distilled or deionized water into a second glass beaker. Pour the pH-electrode cleaning solution into a third beaker. Be sure that there is enough water and cleaning solution in each beaker to thoroughly cover and clean the glass probe
    • Measure the substance's pH level. Take the pH meter electrode probe out of it storage solution, rinse it with distilled or deionized water and wipe it clean with a Kimwipe. Proceed to take the measurement of the substance's pH level
    • Clean to pH meter's probe. Immediately after measuring the pH level of the substance, soak the probe in the beaker of pH-electrode cleaning solution for the approximately 30 minutes or more, depending on how thoroughly it needs to be cleaned. After that, rinse the probe with distilled or deionized water and blot the probe with a clean Kimwipe to absorb any remaining water. Insert the probe back into its storage container filled with a solution with a pH of 3
