SX716

DO Meter

Introduction

● 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.
● Built-in microprocessor chips, intelligent functions such as automatic calibration, data storage, function set-up, automatic power-off and low voltage display.
● Combined diaphragm cap, replaceable sensitive membrane, screw new diaphragm cap to electrode, easy to use.
● Meter meets IP57 waterproof rating, equipped with portable case.
