Portable type DO Meter

D.O. 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°C with 0.1 resolution.  This meter also allows manual compensation of altitude up to 4000 m 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 readings on the LCD.  HI 9146 can be powered with batteries (with low battery indicator) or through a 12 VDC adapter.
