The 2005086.VIT is a Nitrate Ion Electrode Cartridge (NO3). The measurement range is 0.1 ppm to 14,000 ppm, the temperature range is -0°C to 40°C. The 2005086.VIT has a PVC/ion exchange membrane. The NO3 electrode is designed for use in aqueous solutions only, any organic solvents present in the sample will attack the membrane.
The Nitrate Ion Electrode is an ion exchange sensor that is selective for nitrate ions but many anions also interact with the sensing membrane. Chlorate, iodide, cyanide and chlorite ions all strongly interfere with the measurement. Bromide, bisulfide and nitrite interact at 20 to 40:1 with chloride, carbonate and bicarbonate interacting 250 to 500:1. The chloride ion is very common in water and with 250 chloride ions generating the same signal as 1 nitrate ion.
Wetted materials are PES, PTFE, PVC and VITON. Use code "080" to order the 2005086.VIT in an S80 sensor.
