Conductivity Measurement using SE 604 2-Electrode Cell<br />

The SE 604 2-electrode cell is used for measuring extremely low conductivity values. Combined with<br />

the AR 200 flow-through fitting, it is particularly suited for measurements in ultra-pure water (boiler<br />

feed water), for example.<br />
