YSI 5905 Series Self-stirring BOD Probes

The YSI Model 5905 BOD (Biochemical Oxygen Demand) probe is used for measuring dissolved oxygen in all popular size BOD bottles. These probes are self stirring and feature easily replaceable membrane caps and a refurbishable electrode system.

The 5905 is designed for use with all YSI grey-box-style dissolved oxygen meters, except for the Model 55 or Model 550A. It must be used with an adapter (5011) in order to be used on the Model 5000 and 5100 bench top instruments.

The 5905 BOD probe is intended for laboratory use, not field use. It is not waterproof and should never be immersed past the taper on the stem of the probe.
