DOS-118 portable dissolved oxygen meter

●Overview

   DOS-118 portable dissolved oxygen meter wins the ultra-low power single-chip microcomputer measurement control, low power consumption, high reliability, can achieve intelligent measurement, using polarographic measurement, stable reliable, simple convenient operation (one-handed Operation) other advantages; the instrument can indicate the measurement results in two units of dissolved oxygen content, that is, oxygen concentration (mg/L ppm) oxygen saturation percentage (%), in addition to the temperature of the measured medium Perform measurement display.

  The instrument has computer program control calibration, automatic temperature compensation, salinity correction atmospheric pressure adjustment functions, suitable for the measurement of oxygen content in aqueous solutions in various industries.
