    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.
    On most 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 quality control of swimming pool water, in the control of sterilization of drinking water.
    HI 991003 is equipped the Special Sensor Check feature to check the status of the sensor. By means of the pH scale in mV fact it is possible to verify the characteristics of slope and offset of the sensor, and then evaluated according to these values ​​if the operating conditions are within acceptable limits.
    HI 991 003 is robust and equipped with watertight body: particularly therefore suitable for measurements in the field and in industrial environments. The large display at two levels simultaneously displays the values ​​of pH or ORP and temperature.
