GENERAL DESCRIPTION
The Hanna HI 9146 is a water-resistant,
microprocessor-based, auto-calibrating
Dissolved Oxygen meter with ATC. It has been
developed for dissolved oxygen and temperature
measurement in water and wastewater as well
as other applications such as fish farming.
Dissolved oxygen is indicated in hundredths of
parts per million (ppm=mg/L) or in % of
saturation .
The temperature range is indicated in centigrade
from 0 to 50°C with 0.1°C resolution.
The ppm and the % saturation are both
compensated for changes in solubility of oxygen
in water and for permeability of the membrane
as well as the temperature effect.
