Product Description
The Type 8221 hygienic conductivity probes are used to determine electrical conductivity in a wide range of pure or concentrated liquids. Due to their hygienic and robust design, these conductivity probes are suitable for use in various application sectors, including the food & beverage, pharmaceutical, biotechnology and chemical industry. They are available in two technologies, with either 2 or 4 electrodes. Probes based on the 2-electrode principle are intended for use in pure liquids, particularly ultrapure water, as contamination affects the measurement. Probes based on the 4-electrode principle prevent polarisation phenomena and are not sensitive to contamination. The clever design guarantees an excellent linearity over the entire measurement range. All variants are fitted with an integrated temperature sensor (Pt1000) as standard. The probe has to be connected to the multiCELL transmitter/controller Type 8619.
