Press Release Summary:
While models SD7500CD and SD7500CD-ORP are universally compatible with any conventional pH/ORP transmitter or controller, models SD7420CD and SD7420CD-ORP includeÂ direct 4–20 mA output for integration into process control systems. All models utilize 3-electrode differential sensor design that minimizes maintenanceÂ and downtime, extends sensor life, and promotes reliability. Inner reference electrode is surrounded byÂ known concentrated pH 7 buffer that resists process contamination.

Sensorex Expands SD7000 Differential pH/ORP Sensor Line
New models compatible with a wider range of process monitoring systems for water, wastewater, environmental scrubber and other challenging applications
Garden Grove, California – Sensorex has expanded its SD7000 family of Differential pH/ORP Sensors, adding four new models to suit a wider range of online process monitoring applications. Sensorex’s proven differential sensor technology produces highly accurate measurements with an overall low cost of ownership. They are ideally suited for measuring pH and ORP in industrial and municipal wastewater treatment and neutralization; metal finishing and plating; wet fume scrubbers; chemical processing; and other online water quality and process applications.
The three electrode differential sensor design results in less maintenance for operators, minimized down time, longer sensor life and overall greater reliability. Process pH or ORP is measured differentially with process and protected inner reference electrodes, compared to a third ground electrode. The inner reference electrode is surrounded by a known concentrated pH 7 buffer that resists process contamination, maintaining its pH level with minimal dilution effects. A double junction salt bridge further guards against contamination. Both the standard pH 7 cell solution and salt bridge can be replaced periodically at a much lower cost than total sensor replacement.
The new SD7500CD and SD7500CD-ORP are universally compatible with any conventional pH/ORP transmitter or controller, including Sensorex products. The new SD7420CD and SD7420CD-ORP include a direct 4-20mA output for integration into process control systems without requiring an additional 4-20mA transmitter or controller. These sensors are also a direct replacement option for some Hach® and Water Analytics®/Aquametrix probes, as follows:
Hach 6428P0 (LCP body)
Hach 6422P0 (Ryton body)
Water Analytics P65C-8 pH (CPVC Body)
Hach 2428R0 (LCP body)
Hach 2422R0 (Ryton body)
Water Analytics R65C-8 (CPVC body)
