    อุปกรณ์วัด pH (pH meter with analog output for educational purposes)

    HI 22091-02
    pH meter with analog output for educational purposes

    HI 2209 is a pH meter workshop, designed for maximum ease of use. Its features make it the ideal tool for educational workshops for those who want to deal with the first measures pH in a simple and complete.
    instrument performs, in addition to pH, ORP measurements also in mV. The display is large and easy to see and keyboard commands are clear and intuitive.
    measures pH or ORP are made ​​by simply pressing a button. Solid knobs on the front of the instrument used for the calibration, which is performed only manually adjusting the offset points and slope, in order to better understand the students the procedure and the characteristics of the electrode. Another knob is used for manual temperature compensation, and during the adjustment, the display shows the values ​​of the latter together with pH, so that you can clearly explain to students the effect of temperature measurements.
    The Model HI 22091 is also equipped with an analog output for recorder to 0-5 V.
