If you’ve ever wanted to depend on the stability of a STELTH reference electrode for your CIS or DCVG studies, the STELTH 3 portable is for you. Our STELTH 3 portable has the same ceramic rounded tip as our time-tested STELTH 1 – but with a wing nut instead of a wire at the end – making it ideal for use above ground or with Miller Electrode Extensions.

The innovative ceramic tip also features our proprietary Moisture-Retention Membrane (MRM™), which lets moisture in, traps it within the ceramic, and keeps the cell’s internal electrolytes from leeching out.

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

• Never need recharging or recalibrating
• Impregnated with membrane that keeps electrolytes from drying out or getting contaminated
• Trap hydrogen sulfide or excess chloride ions before they cause damage
• Let you know when you have dangerous levels of AC to deal with
• Can thrive in ALL environments, even those chemically detrimental to other reference electrodes
• Remain accurate for their lifetime
• Won’t die every winter

BORIN stands behind every STELTH reference electrode you buy:

• We test EVERY SINGLE reference electrode we make
• 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 after you retire
