Sensors Measure Ammonium Activity

Electro-Chemical Devices (ECD) has launched the MVS10 and MVS17 ammonium pIon sensors. Providing a stable in-line measurement platform, the MVS10 and MVS17 pIon electrode cartridges measure the activity of “free” ammonium ions in solution in concentrations from 0.1 to 14,000 ppm over a pH range from 2-8 pH (2-10.5 pH with pH compensation).

Featuring temperature and pressure specifications, the MVS10 and MVS17 operate over a wide temperature range of 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit) and at a pressure range of 0-50 psig (0-3.5 bar). The sensors also use replaceable, long-life electrode cartridges for measurement flexibility and lower operating costs.

The MVS10 sensor is an insertion- or immersion-style sensor, used in pipe tees or on the end of a stand pipe for immersion into a tank or pond, while the MVS17 is a valve-retractable design that allows for insertion or removal of the sensor into a pipe without interrupting the process flow. Both can be fully rebuilt. 

In addition to ammonium, the sensors are available in models measuring pH, ORP, dissolved oxygen, conductivity, resistivity and other specific ions including bromide, calcium, chloride, copper, cyanide, fluoride, potassium, sodium and sulfide. They also can be used with the T23, 4-20 mA transmitter or integrated with ECD’s C22 analyzer.
