main feature:

Can be carried out Dissolved oxygen concentration, Dissolved oxygen Saturation, electrode current and temperature measurements

With automatic temperature compensation, can be zero oxygen calibration, full scale calibration, barometric calibration and salinity calibration

With data power protection, automatic shutdown and other power management functions, the measurement results can be stored, deleted, access to up to 250 sets of measurements can be stored in the experimental data

With RS-232 interface, can be accessed by TP-16 printer to print the current measurement results or stored data can also be accessed by computer communications

Using a wide-screen LCD display, while operating with tips, easy to use

Protection class IP65, waterproof and dustproof, suitable for field work
