SE571 pH Sensor

The SE571 is a digital Memosens pH sensor engineered for demanding process applications such as high ionic strength media, salt brines, strongly oxidizing solutions and contaminated acidic or alkaline streams. Its PTFE ring junction keeps the reference system in direct, low-blockage contact with the process, while a salt reservoir and special cartridge reference element protect against leaching and poisoning for long-term stability. Galvanic isolation via Memosens technology eliminates moisture-related connector issues, enables lab precalibration and supports integrated sensor diagnostics with minimal maintenance.
