WTW presents conductivity cells.
Models LRD 01 and LRD 325 are suited for fitting in pipes. Model LR 325/01 is ideal for ultra-pure water systems. Model LR 325/001 is suited for trace measurement.
LRD 01 is made of 316 Ti stainless steel. It has an integrated temperature sensor with maximum limit of 130°C. Its measurement range is between 0.01 to 200 µS/cm. It has a 1/2 inch NPT thread, and it can resist pressure up to 14 bar.
