    อุปกรณ์วัด pH (pH / mV)

    PH 21-02
    pH / mV

    The philosophy HANNA instruments ® has always been paid to the different needs of users working in various fields and for this reason are born different classes of instrumentation 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 industry, textile, water treatment and sanitation as well as the engineering industry, paper mill and tannery.
    pH 21 was born as a result of this idea: compact and easy to use, allows you to make quick checks and is suitable for learning environments, where you start to get familiar with the world of the measure.
    instrument provides measurements with centesimal resolution and thanks to the 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).
