YSI® Replacement Dissolved Oxygen (D.O.) Probes

These are the newest dissolved oxygen probes for YSI® 50 Series meters (except Y55). They are designed for those who like the convenience of a screw-on type cap membrane. The body is weighted for quick sinking and is made with the cable attached in 10', 25' and 50' lengths. Included with each probe is a package of six screw-on membranes and electrolyte solution.

Note: YSI recycles all instruments, probes and cables. Learn more about YSI's recycling program.
