Application
Tips: Can the chloride sensor be used in high-salinity or seawater environments?
Yes, this chloride ion-selective electrode is specifically designed to handle a wide range of chloride concentrations, from as low as 1.8 ppm to as high as 35,500 ppm. This makes it especially suitable for high-salinity conditions such as seawater, brackish water, and industrial brine systems. The materials used—PPS—offer excellent resistance to corrosion caused by high chloride content, and the sensor's membrane is engineered to remain stable even in extreme ion activity. This ensures long-term, accurate monitoring without frequent recalibration or membrane degradation.
