ELEMENT Design Conductivity Meter
The Bürkert conductivity meter Type 8222 is designed for measuring the conductivity of fluids. The sensor element comprises a two-electrode cell and a Pt1000 temperature probe. The sensor itself is available with three different cell constants C. These with C=0.01 or 0.1 cm-1 are fitted with stainless steel electrodes and those with C=1.0 cm-1 are fitted with graphite electrodes. Thus, due to the measurement device’s design, Bürkert has simplified installation and maintenance work. The device Type 8222 is available in two variants: The first one, the so-called ELEMENT standard is proposed either with three adjustable outputs (two digital outputs and one analogue output) or with four adjustable outputs (two digital and two analogue) and can be equipped with a display.
