8221导电传感器

The 8221 Hygienic conductivity sensors are usedto determine electrical conductivity in solutions.Due to their hygienic design and the robust layout,these conductivity sensors are suitable for use under demanding conditions in food & beverage,pharmaceutical, biotechnology and the general chemical industry.The sensors are based on the 4-electrode principle which excludes polarization phenomena normally observed with 2-electrode sensors.The engineered design guarantees an excellent linearity over a wide conductivity range of more than 6 decades. An integrated temperature sensor (Pt1000) is a standard feature of all versions Technical data – Electrode。
