    อุปกรณ์วัด pH (pH indicator Ready ® with alarm light for water treatment)

    HI 981402
    pH indicator Ready ® with alarm light for water treatment

    HI 981402 is a robust pH meter made ​​for the continuous monitoring, equipped with liquid crystal display. It is supplied with HI 1286 electrode with plastic body, double junction and gel electrolyte.
    This special electrode with PTFE diaphragm, it is very resistant to clogging and thus suitable for industrial control of the waters. It replaces it with ease thanks to the BNC connector which is always protected by a rubber sheath.
    HI 981402 is equipped with a red alarm LED that lights up if the threshold set by the user (selectable from 3 to 11 pH) is exceeded by a value greater than about 0.5 pH (hysteresis).
    calibration is performed manually at 1 or 2 points by means of the front trimmers. With the body being protected from splashes, HI 981402 is suitable for installation in harsh environments with high humidity or dust. The practical hook allows you to secure the instrument directly to the desired point. The 12 Vdc power supplied allows continuous control without interruption.
