pH Sensor for Simple Water Applications
The SE 515 Memosens pH sensor is ideal for use in water and wastewater treatment applications.
The sensor is designed to withstand plugging media, low temperatures, and to maintain a reliable measurement in low-ionic media. An integrated NTC 30K temperature element assures that all pH measurements are accurately compensated for the temperature of the process media. The low price of this sensor, along with the integration of Memosens technology, provide for a significant reduction in the overall cost of ownership.
The SE 515 is suitable for use with any Memosens transmitter. However, when paired with the MemoRail transmitter it provides for one of the lowest-priced digital pH measurement loops on the market.
