YSI 54ARC Dissolved Oxygen Meter with Power Cord

The YSI 54ARC dissolved oxygen meters are intended for dissolved oxygen and temperature measurement in water and wastewater applications, but are also suitable for use in certain other liquids. Dissolved oxygen is indicated in PPM (parts per million) on 0-10 and 0-20 PPM scales. Temperature is indicated in °C on a 5 to +459C scale. Both dissolved oxygen ranges are automatically temperature compensated for solubility of oxygen in water and permeability of the probe membrane. Power to operate the system is provided by rechargeable internal batteries (not included). This unit requires the power cord to function.
