Reference Electrodes

STELTH 9®

Solid-State Reference Electrodes 

For Deep Water Service

If it’s deep water or fast flowing water applications you’re dealing with, our STELTH 9 reference electrode is for you. It has been designed specifically for your projects that require a reference electrode to be immersed in water (sea, brackish, or fresh water, depending on the chemistry you choose) as its crush-proof body will withstand the high pressures or rapid flow at any depth, up to 6,000 feet (1,800 meter) 

The STELTH 9 comes with two parts: the core side made with high-impact ABS protecting the ceramic and reference electrode inside, and the interchangeable longer, weighted side made of sturdy high-impact ABS housing and calibrated added weight. Both pieces will not deteriorate, even in highly-corrosive environments and will inhibit marine growth. 

Thanks to its rugged design, the STELTH 9 reference electrode requires no maintenance of any kind. 

Depending on the chemistry you choose the STELTH 9 can be used in both fresh water and/or high-chloride water service (such as the ocean).

  • Just a few reasons BORIN STELTH solid-state reference electrodes are unique: 

    • Never need recharging or re-calibrating 

    • Impregnated with membrane that keeps electrolytes from drying out or getting contaminated  

    • Trap hydrogen sulfide or excess chloride ions to maintain stability of the electrode 

    • Let you know when you have dangerous levels of AC to deal with

    • Can thrive in ALL saturated environments for their corresponding chemistry

    • Remain accurate for their lifetime

    • Can survive in all winter conditions 

    • No need for antifreeze that could alter your readings 


    BORIN stands behind every STELTH reference electrode you buy:

    • We test EVERY SINGLE reference electrode we make. For more details see testing criteria

    • You can track/trace any STELTH

    • Every STELTH is calibrated for the life of the cell

    • Our STELTH reference electrodes will work for years and remain stable indefinitely
