Vernier Ion-Selective Electrodes

|
Great for studying four environmentally important ions: Nitrate (NO3), Chloride (Cl), Calcium (Ca2+), and Ammonium (NH4+). The electrodes are combination-style, non-refillable, and gel-filled.
Nitrate Ion-Selective Electrode
Nitrate ion concentration is an important parameter in nearly all water quality studies. Nitrates can be introduced by acidic rainfall, fertilizer runoff from fields, and plant or animal decay or waste.
Chloride Ion-Selective Electrode
This electrode gives a quick measurement of salinity of water samples. It can even measure chloride levels in ocean saltwater or salt in food samples.
Calcium Ion-Selective Electrode
This electrode gives a good indication of hardness of water (as Ca2+). It is also used as an endpoint indicator in EDTA-Ca/Mg hardwater titrations.
Ammonium Ion-Selective Electrode
This electrode measures levels of ammonium ions introduced from fertilizers. It can also indicate aqueous ammonia levels if sample solutions are acidified to convert NH3 to NH4+.
