* This temperature specification is only for the Star Plus RDO optical dissolved
oxygen meter when it is used with the RDO optical dissolved oxygen sensor.
The 4-Star and 5-Star RDO meters will have the standard temperature
specifications when used with an electrode other than the RDO sensor.
Note: Specifications are subject to change without notice.
