Online conductivity meter, resistivity meter, acid-base concentration meter
Liquisys M OLM223 and OLM253 conductivity meters adopt modular design and are widely used. The basic transmission provides simple measurement and alarm functions, and the software and hardware modules for extended functions can be applied to special occasions. If necessary, expansion modules can be used.
Application of German AMER online conductivity meter OLM223/OLM253
