pH and ORP measurements are widely used throughout all industries for monitoring and control of process liquids and water quality. But how many people really know the proper calibration techniques? And furthermore, do you really know what the calibration results are telling you? Come to the ISALA meeting on Tuesday, September 16th to get all of your questions answered.

This presentation will feature Dr. Steve Wells, a well known PhD chemist from Georg Fischer Signet LLC who will provide practical information for using pH and ORP sensors. An overview of how and why these electrochemical sensors need calibration will be discussed. A brief explanation of pH and ORP sensor designs will enhance your understanding of your calibration results. Other issues like two point calibration, single point (otherwise known as standardization) calibration, sensor storage, and sensor troubleshooting will be covered.

Dr. Steve Wells, Senior Chemical Engineer at George Fischer Signet, manages analytical sensor research and development. He has extensive experience in research & development working on potentiometric and amperometric sensors. Dr. Wells possesses an extensive background with his Bachelor of Science degree in Biology and Chemistry from University of California, Irvine. He received his PhD in Physical Chemistry at UC Irvine specializing in surface chemistry and physics.
