A top of the line analyzer would be from World Precision Instruments, but brace yourself as they are expensive. YSI can hold its own as well.

Before buying a new one, you might check your flow conditions: is there opportunity for atmospheric oxygen to infiltrate (e.g., through a long span of silicone tubing or in a open cup, especially if flow rates are low).
