DOS-118 Portable Dissolved Oxygen Meter

DOS-118 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.
The instrument has a computer program: Control calibration, automatic temperature compensation, salinity and atmospheric correction adjustment function, suitable for measuring the oxygen content in the various sectors of the aqueous solution.
