HI 9146 is a water - resistant, dissolved oxygen meter that
measures up to 300% saturation or 45 ppm (mg/L) with
temperature compensation and automatic calibration.
It has been developed for DO and temperature
measurement in water, wastewater, wine and applications
such as fish farming.
This instrument also allows altitude compensation up
to 4000 m and the ppm and % saturation are both
compensated for changes in solubility of oxygen in water
and for permeability of the membrane as well as the
temperature effect.
The included polarographic probe features built - in
temperature compensation and removable protective
membrane cover.
