Online Dissolved Oxygen Controller LODC-A10 features 1 to 2 points dissolved oxygen calibration system, and 4 to 20 mA output signal transmitter. The large and clear back light LCD displays Calibration and setup values, temperature values, ATC (automatic temperature compensation) values, high and low limit of measurement. It measures the amount of dissolved oxygen in mg/l, ppm units or in % of saturation. The accuracy of measurement is improved by manual salinity and barometric pressure compensation mode.
