Why need to measure the dissolved oxygen?
For aquaculture, if dissolved oxygen levels are too low, fish can
suffocate and die as a result. In wastewater treatment plants,
bacteria break down solids. If DO levels are too low, bacteria die
and decomposition stops; if dissolved oxygen levels are too high,
then energy is wasted through aeration of the water. In industrial
applications, including boilers, supplemental water must have low
DO levels to avoid corrosion and boiler fouling. Monitoring
dissolved oxygen levels is critical to ensure process efficiency,
as boiler fouling inhibits heat transfer. High dissolved oxygen
levels in water can improve the taste of drinking water. However,
high dissolved oxygen levels can increase corrosion in water pipes
and transport lines.
Portable dissolved oxygen meter is outstanding for ultra-low power microcontroller measurement and control, low power consumption, high reliability, intelligent measurement, using polarographic measurements, without changing the oxygen membrane. Having reliable, easy (one-hand operation) operation, etc.; the instrument can display dissolved oxygen concentration in two kinds of measurement results indicates, mg / L (ppm) and the oxygen saturation percentage (% ), in addition, measure the temperature of the measured medium simultaneously.
