Benchtop Dissolved Oxygen Meter - Touch Screen DO Meter - 0.00-99.99 ppm - 0-600% Saturation

The Master Science Benchtop Dissolved Oxygen Meter measures oxygen concentration from 0.00 to 99.99 ppm and saturation from 0 to 600% with a polarographic sensor. Temperature is read by the same probe.

Results are corrected automatically for temperature and barometric pressure, and a salinity factor can be entered by hand. A colour touch screen runs an operating system with user, calibration, method and data management.
