Omega Engineering's system comes in two models (concentration or conductivity) and is available in three power versions: loop, AC or battery. The CDTX-45T toroidal conductivity system is designed for inline monitoring of chemically aggressive process solutions, water applications that coat or foul traditional sensors and plating bath operations in which high current densities are present. The CDTX-45TC is the concentration monitor that comes with concentration/temperature tables for sodium hydroxide, potassium hydroxide, hydrochloric acid, nitric acid and sulfuric acid. A configurable table allows the user to enter data points for a custom concentration curve. Dual alarm relays/analog outputs and a large, easy-to-read two-line display make these instruments handy.
