YOKOGAWA ISC450G 4-Wire Inductive Conductivity Analyzer |
YOKOGAWA ISC450G 4-Wire Inductive Conductivity Analyzer
The EXAxt 450 will help you and guide you as the unique Human Machine Interface (HMI) will not only present you reliable process data, but diagnostics, trends, logbooks and step by step calibration routines to become your friend in analytical measurement and help you gaining that higher level of quality. The high resolution graphical display and the touchscreen operation make all information visible to the operator.
The ISC450G is designed to measure specific conductivity by using the inductive conductivity method. This method is especially suitable for high conductivity measurements. The ISC450G features a unique accuracy and rangeability, which is only possible through superior sensor design and electronic data processing using a self tuning preamplifier with more than 10 sub ranges with automatic zero adjustment at every range change.
Accurate concentration measurement requires accurate temperature compensation and the ISC450G offers three compensation methods from default NaCl compensation to user defined MATRIX compensation for electrolytes where the coefficient varies with temperature and with concentration.
