D O Meter microprocessor photo colorimeter and set the timer onD O Meter LMDO 50 use a polarographic electrode to measures dissolved oxygen in water, it can display the oxygen level as % saturation from 0 to 200% or concentration from 0 to 20ppm (mg L). One or Two points calibration (100% in air, 0% in zero oxygen solution) Automatic temperature compensation for best accuracy under fluctuating temperatures Automatically compensates salinity and barometric pressure after manual input for increased accuracy
