. The pH/ORP Flow-through Sensor Type 6970 offers a robust solution for difficult process measurements. A continuous flow of sample solution is delivered from and returned to the process by a pneumatic sample pump to allow simultaneous measurement of pH and ORP (millivolts). Features include...

• Stainless steel sensor construction with glass sample resevoir keeps electrodes immersed at all times greatly extending electrode life.
• Integrated stainless steel RTD provides temperature compensation.
• Interface Type 6995A provides connection between electrodes and RTD and the Model 7766.
• Strandberg recommends use of gel-filled pH and ORP electrodes for low maintenance.
