Hanna Instruments HI 9146-04 Portable Dissolved Oxygen Meter with HI 76407/4 DO Probe with 4 m cable

The Hanna Instruments HI 9146 Portable Dissolved Oxygen Meter with Standard DO Probe is a water-resistant, dissolved oxygen meter that measures up to 300% saturation or 45 ppm (mg/L) with temperature compensation and automatic calibration. The Hanna Instruments HI 9146 has been developed for DO and temperature measurement in water, wastewater, wine and applications such as fish farming. + The Hanna Instruments HI9146 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.
