    อุปกรณ์วัด pH (pH meter watertight and read pH, mV (pH), ORP and temperature)

    HI 991003
    pH meter watertight and read pH, mV (pH), ORP and temperature

    HI 991003 pH, pH (mV), ORP and temperature with a single electrode.
    In most of the other pH meters is necessary to remove the pH electrode and insert the ORP electrode, or vice versa. HI 991003 allows instead of having the two readings at the same time.
    HI 991003 is widely used in the control of plant water purification galvanic, in the monitoring of water quality of swimming pools, in the control of sterilization of drinking water.
    HI 991003 is equipped Special Sensor Check the function for checking the status of the sensor. By means of the pH scale in mV in fact it is possible to verify the characteristics of slope and offset of the sensor, and then evaluate on the basis of these values ​​if the operating conditions are within acceptable limits.
    HI 991003 is equipped with robust and watertight housing: especially therefore suitable measures in the field and in industrial environments. The large dual level display simultaneously displays the values ​​of pH or ORP and temperature.
