The YSI model 54ARC dissolved oxygen meter is intended for dissolved oxygen and temperature measurement in water and wastewater applications, but is also suitable for use in other liquids. Dissolved Oxygen is indicated in mg/l (milligrans per liter) on 0-10 and 0-20 mg/l scales. Temperatures is indicated in degrees Celsius on a -5 degrees to +45 degree scale. Both dissolved oxygen ranges are automatically temperature compensated for solubility of oxygen in water and permeability of the probe membrane.
