Differential ph/ORP sensors


Sensorex’s SD7000 Series differential pH/ORP sensors offer water, wastewater and process plant operators a new measurement method based on proven sensor technology. The differential electrode technique employs three electrodes. Solution pH is measured differentially with process (outer hemi glass) and inner reference (surrounded by a known concentrated pH 7 buffer) electrodes. This provides optimal measurement accuracy, minimizes reference junction potential and eliminates sensor ground loop effects. Differential sensor design results in less maintenance for operators, minimized down time, longer sensor life and overall greater reliability. http://www.sensorex.com, sales@sensorex.com
