Description:

The new EXAxt 450 series builds on the superior functionality of the industry leading Yokogawa EXA series by enhancing the EXA's proven operation and application flexibility. The Model 450 series feature a uniquely simple touch screen menu structure that offers a choice of multiple languages. The Model PH450 provides the best pH measurement accuracy in the industry resulting from advanced temperature compensation functionality, preloaded calibration standards, stability checks and online sensor and analyzer diagnostics to provide verifiable results. In addition to dynamic sensor checking, the Model 450 offers a wash cycle function to assure trouble free and accurate analysis with a minimum of maintenance. The EXAxt 450 also offers full application functionality with PID control on either mA output(s) or on contact output(s). The PH450 combines pH with Temperature and ORP (Redox) measurement that can be utilized though different output functions: two mA outputs, four independent SPDT contact outputs and a digital HART signal is superimposed on mA1. This information can be used to generate additional current and contact outputs in the HIM monitor and in maintenance optimization programs like PRM or AMS. The EXAxt 450 series provides a truly unique Human Machine Interface. The high resolution graphical display and touch screen operation provides all information clearly visible and easily accessible to the operator. Simply select the language of choice and on screen instructions assure that the best configuration for the application is obtained.……
