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.
