DOS-1703 Portable Dissolved Oxygen Meter
DOS-1703 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.
