 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 pH electrode and dissolved oxygen electrode, automatic identification of electrode by meter.
● Automatic identification of 13 pH standard buffer 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.
● Measurement mode of Dissolved oxygen has the function of automatic temperature compensation, automatic salinity compensation and manual air pressure compensation.
● New polarographic type dissolved oxygen electrode can measure temperature, salinity and dissolved oxygen simultaneously, equipped with special dissolved oxygen electode calibration set, polarization only for 3~5 min.
● Meter meets IP57 waterproof rating, equipped with calibration solution and portable case.
