    อุปกรณ์วัด pH (Waterproof pHtester with replaceable electrode)

    HI 98128
    Waterproof pHtester with replaceable electrode

    When HANNA instruments introduced in 1986 the first version of pHep ® , the first handheld electronic pHtester, revolutionized the habits in pH measurement.
    Ease of use pHep ® , combined with its reliability, made ​​it possible to perform pH measurements on a sample with precision and very low cost in any type of industrial application and control. Since then, more than 4 million pHep ® have been successfully used by our customers all over the world.
    From suggestions and demands of these customers were born the new ideas that led to the creation of the last series of these tools.
    pHep ® 5 has innovative features such as dual level display, the indicator of the level of battery charge, the electrode can be easily replaced, the indicator of instability of the measure, the sleep mode, automatic calibration and body watertight floating .
