Portable pH/ORP Meter

Portable pH/ORP Meter
ELE-721

Introduction:

  • 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.
