Product Description Conductivity monitor with flow cell for up to 100 ml/min and optional pH measurement Conductivity monitor with optional pH measurement The AZURA CM 2.1S is a reliable conductivity monitor which is usually utilized in FPLC to follow salt gradients. By adding a pH sensor also pH values can be measured. Wetted parts are completely biocompatible. The contactless measurements of conductivity reduces the risk of carryover to a minimum. The flow cell covers a flow rate up to 100 ml/min and is delivered with the CM 2.1S.
