The YSI Pro20 is a handheld meter used to measure the amount of dissolved oxygen in groundwater, wastewater, aquaculture, and surface water. The Pro20 can be used in the field using a polarographic or galvanic sensor or a self-stirring BOD probe for DO sampling in a lab.
All sensors and cables are user-replaceable. The polorographic sensor needs time to warm-up before it can be used, but it costs less than the galvanic probe. You'll pay more for a Galvanic probe, but it lets you start sampling right away without a warm-up period.
When ordering the YSI Pro20 DO, the instrument, cable, and dissolved oxygen probe must be ordered separately in order to choose the system that best fits your application.
