    อุปกรณ์วัด pH (pH / mV)

    PH 2.21
    pH / mV

    The philosophy HANNA instruments ® has always been paid to the different needs of users working in various fields and for this reason they were born different classes of instruments for the measurement of a single parameter.
    Measuring the pH is extremely important in all those areas where the ‘Water plays an important role: the food, textile, water treatment and sanitation as well as the metal industry, paper and leather.
    pH 21 is born as a result of this idea: compact and easy to use, allows for quick checks and is suitable for learning environments, where you start to become familiar with the world of the measure.
    instrument provides measurements with a resolution of thanks to the foil and mV readings can also be used for ORP measurements. To provide the user with complete information about the analyzed sample measurements can be manually or automatically compensated in temperature due to the HI 7662 probe (optional).
