 The circuit gives 0.5% accurate readings for pH values from 0 to 14 with greater than 14-bits of noise-free code resolution and is suitable for a variety of industrial applications such as chemical, food processing, water, and wastewater analysis.   The circuit gives 0.5% accurate readings for pH values from 0 to 14 with greater than 14-bits of noise-free code resolution and is suitable for a variety of industrial applications such as chemical, food processing, water, and wastewater analysis.  
 This circuit supports a wide variety of pH sensors that have very high internal resistance that can range from 1 MΩ to several GΩ, and digital signal and power isolation provides immunity to noise and transient voltages often encountered in harsh industrial environments.  For general board details and to buy a board please visit the [[ADI>EVAL-CN0326-PMDZ]] product page. This circuit supports a wide variety of pH sensors that have very high internal resistance that can range from 1 MΩ to several GΩ, and digital signal and power isolation provides immunity to noise and transient voltages often encountered in harsh industrial environments.  For general board details and to buy a board please visit the [[ADI>EVAL-CN0326-PMDZ]] product page.

-When using the CN0326 PMOD board, a general purpose pH probe with BNC connecter can be used for pH measurement.  An example of a pH probe that can be used is a product from [[https://www.atlas-scientific.com/product_pages/probes/ph_probe.html|Atlas]] or from [[https://www.hach.com/radiometer-probes/radiometer-analytical-probes/family?productCategoryId=35547627768|Hach]].  For temperature compensation, an RTD  sensor with RCA connector can be used.  An example is from [[https://www.atlas-scientific.com/product_pages/probes/pt1000.html|Atlas]] or from [[http://sea.omega.com/ph/subsection/rtd-elements-with-lead-wires-attached.html|Omega]].  These sensors are required in order to run and capture analog signal from a sample solution.  +When using the CN0326 PMOD board, a general purpose pH probe with BNC connecter can be used for pH measurement.  An example of a pH probe that can be used is a product from [[https://www.atlas-scientific.com/product_pages/probes/ph_probe.html|Atlas]] or from [[https://www.hach.com/radiometer-probes/radiometer-analytical-probes/family?productCategoryId=35547627768|Hach]].  For temperature compensation, an RTD  sensor with RCA connector can be used.  An example is from [[https://www.atlas-scientific.com/product_pages/probes/pt1000.html|Atlas]] or from [[http://sea.omega.com/ph/subsection/rtd-elements-with-lead-wires-attached.html|Omega]].  These sensors are required in order to run and capture analog signal from a sample solution and the connections can be seen on the diagram as shown below.
