Dissolved Oxygen Meter

HANNA HI 9146 is a water-resistant, microprocessor-based, Dissolved Oxygen meter with automatic temperature compensation (ATC). 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 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.
