Ideal for meaurement in thick or viscous samples, but compatible with all sample types. The Thermo Scientific™ Orion™ 8165BNWP ROSS™ Sure-Flow™ pH Electrode with waterproof connector provides a clog-resistant, easy-to-clean sleeve junction.


The Orion ROSS Sure-Flow pH Electrode provides field pH measurement where stability and high performance is desired (on-site pH soil). With a waterproof BNC connector, the pH electrode is made of a rugged epoxy body that resistants strong acids and bases.

The unique free-flowing junction cleans easily between measurements; press down on the cap to allow filling solution to flow through the junction and carry away any contaminants that may interfere with measurement. This clog-free feature offers the longest use life. A sleeve protects the pH sensing bulb and removes for easy cleaning.
