There are two families of electrodeless conductivity analyzers. Selection depends on the user’s application requirements. The 875EC is a highly accurate instrument with a very intuitive user interface. The 875EC can be used either for conductivity or concentration measurements. The 873EC analyzer is a basic, 1/4 DIN instrument that is more suited to OEM applications. Both the 875 and the 873 Series accept one sensor input. They provide local indication, two alarm relays and two analog outputs.
