Editor-in-Chief Elisabeth Lisican showcases a handful of features to read in the April 2017 issue of Water & Wastes Digest.
The SD7000 family of Differential pH/ORP Sensors includes four new models to suit a wider range of online process monitoring applications. They feature a three-electrode, differential-sensor design. The SD7500CD and SD7500CD-ORP are universally compatible with any conventional pH/ORP transmitter or controller. The SD7420CD and SD7420CD-ORP include a direct 4-20 mA output for integration into process control systems without requiring an additional 4-20 mA transmitter or controller.
