Continuous online pH monitoring in wastewater and coating industrial applications leads to contamination, and eventually will require for sensors to be replaced. A differential pH sensor utilizes a measurement technique designed specifically to extend the working lifetime of sensors in a challenging application. Replacing the sensor reference (salt bridge) and buffered electrolyte solution can prevent sensor replacements, saving time and money. Our SD7500 Series features a combination sensor output; these differential pH sensors can be used with any conventional pH/ORP transmitter.
Features
- Reliable measurement performance: True differential pH measurement technology uses solution ground
- Extended lifetime: Buffered electrolyte reference solution resists fouling
- High accuracy measurements: Differential measurements virtually eliminate ground loop measurement errors
- Use with any transmitter or controller: Self-powered unit is compatible with any conventional pH transmitter
- Resists aggressive chemicals: Constructed of durable Ryton® Polyphenylene Sulfide (PPS)
