Suitable for aquaculture, water source monitoring, sewage treatment and environmental protection monitoring, especially for outdoor purposes.

●Large LCD screen with controllable white backlight.

●Humanized designs like rack and skid proof shell make it more convenient for users.

● DO mode has functions of ATC, auto salinity compensation and auto pressure compensation.

● New structure polarographic DO electrode can measure temperature, salinity and dissolved oxygen simultaneously, equipped with special DO electrode calibration sleeve, only need 3~5 minutes for polarization.

●Built-in microprocessor chip with functions of auto calibration, auto temperature compensation, data storage, function setup, self-diagnosis, auto power off, low voltage display.

●Combined diaphragm cap makes it extremely convenient to replace the sensitive membrane just by screwing the new cap to the electrode.

●Grade IP57 and equipped with portable carrying case.
