The 875EC is Schneider Electric's intelligent electrodeless (toroidal) conductivity and concentration analyzer - a line-powered unit that reads process fluids through 871EC or 871FT sensors without electrodes touching the liquid.

Why electrodeless instead of contacting cells?

Acids, slurries, and high-concentration solutions coat and polarize contacting electrodes until they read wrong - the toroidal 875EC measures through the pipe wall, so nothing fouls. The alternative is a contacting cell you pull and clean on a schedule.

How do you get concentration, not just µS/cm?

Built-in chemical curves output % by weight, g/L, ppm, or ppt directly, so a dosing loop can run on concentration. The alternative is a separate calculator or a manual table lookup at every batch.

Can it live in a hazardous area?

It ships in a NEMA 4X / IP65 housing certified FM, CSA, ATEX, and IECEx, with dual 4-20 mA outputs, dual relays, and optional HART. The alternative - a panel-only analyzer - stays in the control room, away from the sample point.
