Labs testing fluoride in drinking water, ammonia or nitrate in effluent and sodium in food rely on ion-selective electrodes. This benchtop meter reads ±2000.0 mV at 0.1 mV resolution, covers 1×10⁻⁶ to 1 mol/L depending on electrode and calibrates at 2–5 points plus blank. It also works as a pH meter. Tell us your target ions.
