SX721 portable pH/ORP meter acidity meter mV


Because the battery can not be transported, so you receive the goods do not contain batteries!


  • The most cost effective pH+OPR double-parameter meter, suited for industrial and mining factories, power plant, water treatment project and environmental protection industry, especially suited in field and on-site.
  • ● Built-in microprocessor chips, intelligent functions such as automatic calibration, automatic temperature compensation, data storage, function set-up, self-diagnose information, automatic power-off and low voltage display.
    ● Double-parameter meter, equipped with three-in-one combination pH electrode and ORP electrode, automatic identification of electrode by meter.
    ● Automatic identification of 13 pH standard calibration solutions, three options of standard buffer solutions: Europe and America series, NIST series and China series.
    ● Able to set pH measurement modes of high purity water and pure water with ammonia
    ● Meter meets IP57 rating, equipped with calibration solution and portable case.
