BORIN STELTH 4 – Fat Cat Solid-State Portable Reference Electrode

As with the slimmer STELTH 3 portable, the STELTH 4 Fat Cat is built with a wing nut instead of a wire, making it ideal for use above ground or with Miller Electrode Extensions.

The STELTH 4 Fat Cat also has a convenient flat ceramic plug shape so that you can stand it up on its end for easy readings.

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
