The model FLEXA® two-wire analyzer is used for continuous on-line measurements in industrial applications. It offers an option for single or dual sensor measurement, making it the most flexible 2-wire analyzer available. The model FLEXA® modular-designed series analyzer offers 4 parameter choices – pH/ORP (oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) – with the respective sensor module.
The ISC450 is designed to measure specific conductivity by using the inductive conductivity method. This method is especially suitable for high conductivity measurements. The analyzer works with a sensor that has two, built-in toroidal transformers. AAn AC current induces a voltage in the process sample, giving it its own current. The strength of this current is proportional to the conductivity of the sample following Ohm’s law.
The model SC450 is designed to measure specific conductivity with contacting electrodes. This method is proven to offer very high measurement accuracy especially in pure and ultra pure water applications. The SC450 has a self-tuning pre-amplifier that eliminates measuring errors associated with cabling and reduces polarization caused by high conductivities and cell fouling.
