YSI Pro Optical Dissolved Oxygen 100 FT Meter Rental $60.00 $140.00 $400.00

The YSI ProODO measures dissolved oxygen in water using luminescence technology. The optical DO sensor eliminates the need to stir samples, making it perfect for applications such as deep water profiling where stirring is difficult or undesirable. Unlike other DO measurement technologies, the optical sensor does not consume oxygen during its measurement process.
