SD7420CD - Differential pH Probe, Direct 4-20mA Output

Product Information

Applications such as pulp and paper or dye manufacturing and industrial wastewater treatment may expose pH probes to harsh conditions and chemicals. A differential pH probe utilizes a special measurement technique, which extends the working lifetime of the sensor in challenging applications. Replacing the sensor reference (salt bridge) and buffered electrolyte solution can extend working lifetime, which saves timely, costly replacements. Our SD7420CD features differential sensor technology with a direct 4-20mA output, so it can be integrated into control systems without the use of a transmitter or controller.

• Reliable measurement performance: True differential pH measurement technology using solution ground
• High accuracy measurements: Differential measurement technique virtually eliminates ground loop measurement error
• No transmitter or controller required: Direct 4-20mA output for simple integration
• Resists aggressive chemicals: Constructed of durable Ryton^® Polyphenylene Sulfide (PPS)
• Automatic temperature compensation: Accurate measurements even with rapid temperature changes
• Two Year limited Warranty: We stand behind our products with the Sensorex guarantee

CA Residents: Prop 65 WARNING(S)

For optimal shelf life, store sensors at 15-30°C.
