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.
Salinity compensation in water allows determination of mg/L of dissolved oxygen in
salty waters and the altitude compensation readjusts for the altitude variance.
Four 1.5V AA alkaline batteries provide power and make the instrument completely portable. The Hanna HI 9146 is also designed to be used with a battery recharger or a 12 Vdc power supply. A 12 Vdc input jack is incorporated into the housing.
A microprocessor ensures an accurate and rapid calibration and measurement. The case rugged and water-resistant for maximum protection in the field as well as in the laboratory.
The dissolved oxygen probe has a membrane covering the polarographic sensor elements and a built-in thermistor for temperature measurement and compensation. The thin permeable membrane isolates the sensor elements from the testing solution, but allows oxygen to enter. When a voltage is applied across the sensor, oxygen that passes through the membrane causes a current to flow from which the oxygen concentration is determined.
