    เครื่องโฟโตมิเตอร์-เหล็ก, ความกระด้างทั้งหมด, พีเอช (Iron, Total Hardness and pH Photometer)

    HI 93744

    Iron, Total Hardness and pH Photometer with 555 nm LED

              Three important parameters measured with just one meter! The easy-to-use HI 93744 can replace several meters or test kits to practically perform the same tests with better accuracy.

    At the touch of a button, you can zero you sample. This means that prior to each measurement and literally in a few seconds, your meter is calibrated, ensuring an accurate end result.

    HI 93744 uses an LED that lasts the life of the meter. The unit is powered by a common and inexpensive 9V battery that can provide up to 40 hours of battery life. A built-in automatic shut-off will turn the meter off after 10 minutes of non-use prolonging the battery life.

    The meter housing is made of rugged ABS plastic and the keyboard is splash proof. The unit weighs less than 300 grams (11 ounces) so that it can be packed in the smallest of cases and carried to the remotest sites. HI 93744 is also guaranteed as yet another qualityHANNA® product and backed with a two-year warranty.
