Dissolved Oxygen Meter
This heavy duty dissolved oxygen meter is ideal for testing water, in labs, industrial and municipal waste water, aquariums, fish hatcheries, and environmental applications. Displays dissolved oxygen (mg/l), oxygen in air (%), and temperature (C/F). Meter uses remote polarographic dissolved oxygen sensor. The meter also monitors oxygen in air for indoor air quality and confined space applications. Features automatic temperature compensation. Dissolved oxygen can be read in either mg/L or % oxygen in air, and temperature in °C or °F. Both oxygen and temperature readings are simultaneously displayed.
