The LiquiSonic analyzer (photo) now complies with the increased electromagnetic compatibility (EMC) requirements proposed under the Namur Recommendation NE 21. NE 21 requires that the devices used in laboratory and process control are immune to interference. With the EMC conformity, the function of the LiquiSonic analyzer is not influenced by electromagnetic sources of interference from other devices, nor does the analyzer itself turn into a source of interference to other devices. The LiquiSonic is used for diverse applications, such as determining the concentration of acids and bases, and monitoring of polymerization and crystallization processes. — SensoTech GmbH, Magdeburg-Barleben, Germany
