title
The new S10 and S17 ammonium sensors from Electro-Chemical Devices (ECD) consist of two universal sensors and replaceable electrode cartridges. The S10 sensor is an immersion or an insertion style sensor that uses a 0.75-inch MNPT compression fitting as the process connection, while the S17 is a valve retractable style sensor that uses a 1-inch MNPT ball valve, a 1 × 0.75-inch reducer and a 0.75-inch MNPT compression fitting to provide the process connection. Each sensor:
- Is fully re-buildable.
- Utlizes a 316 stainless steel body that incorporates the sensing element, a temperature module and a signal conditioner with cabling.
- Utilizes ECD’s replaceable electrode cartridges, which can be selected to measure pH, ORP, dissolved oxygen, conductivity and resistivity.
- Features a pIon electrode cartridge that measures the activity of “free” ammonium ions in solution in concentrations from 0.5 to 18,000 ppm over a pH range from 2-10 pH between 0 to 40ºC.
- Can be integrated with ECD’s C22 Analyzer to provide automatic pH compensation for a total ammonia measurement system.
