SX725 Portable pH/Dissolved Oxygen Meter แบบภาคสนาม

SX725 Portable pH/Dissolved Oxygen Meter

The most cost effective portable pH+Dissolved Oxygen double-parameter meter, suited for industrial and mining factories,

power plant, aquaculture and environmental protection field, especially suited in field and on-site.

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.
