1Built-in microprocessor chips 2.intelligent functions 3.automatic temperature compensation 4.Self-diagnose information

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.
