Rugged DO Meter with Extended Range MS 0257 is a water-resistant, microprocessorbased, Dissolved Oxygen Meters with automatic calibration and temperature compensation (ATC). D.O. measurements can be displayed in parts per million (ppm=mg/L) or in % saturation. The temperature range is indicated in Celsius from 0 to 50°C with 0.1 resolution. The MS 0257 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. MS 0257 can be powered with batteries (with low battery indicator) or through a 12 Vdc adapter.
