EHI9146 is a water-resistant, microprocessor-based, dissolved oxygen meter with automatic temperature compensation (ATC). DO measurements can be displayed in parts per million (ppm=mg/L) or in % of saturation. The temperature range is indicated in Celsius from 0 to 50 deg. C with 0.1 resolution. This meter also allows manual compensation of altitude and salinity values. The polarographic probe, supplied with the instrument, is provided with a protective cover for the membrane. A HOLD button allows the user to freeze the reading on the LCD. EHI9146 can be powered with batteries (with low battery indicator) or through a 12 Vdc adapter.
EHI9146-10 is supplied with HI 76407/10F probe with 10m (33') cable and protective cap, 2 spare membranes, HI 7041S electrolyte solution (30mL), batteries, hard carrying case and instructions.
