Yokogawa pH and Redox (ORP) Converter PH450G-A-A/SCT

Yokogawa pH and Redox (ORP) Converter PH450G-A-A/SCT 

The PH450G offers the best accuracy in the industry by combining the pH measurement with advanced temperature compensation functionality, preloaded calibration standards and stability checks. Yokogawa pH and Redox (ORP) Converter PH450G-A-A/SCT

The PH450G is a true multivariable analyzer that combines pH with Temperature and ORP (Redox) measurement and all these measurements can be
utilised through the different output functions: two mA current outputs, four independent SPDT contact outputs and HART®. Both DD and DTM files are available for direct connection to HART® Handheld terminal, HMI monitor and Pactware PC configurator. 

Yokogawa pH and Redox (ORP) Converter PH450G-A-A/SCT
The PH450G offers full functionality with PID control on either mA output(s) or on contact output(s) and with integral wash function.
