: Ammonium selective electrode (ISE) is a
combination liquid membrane sensor used for the detec-
tion of free ammonium-nitrogen in freshwater samples. The
sensor utilizes a polymeric membrane made with ammo-
nium ionophore in a PVC head and silver/silver chloride
double junction gel filled reference electrode. This sensor is
used in place of the pH sensor in the probe.
HI 7609829-11 : : : : : The Chloride ISE is a combination solid state sensor used for
the detection of free chloride ions in freshwater samples. The sensor utilizes a
silver chloride pellet housed in a PEI head and a silver/silver chloride double
junction gel filled reference electrode. This sensor is used in place of the pH
sensor in the probe.
HI 7609829-12 : : : : : The Nitrate ISE is a combination liquid membrane sensor
used for the detection of nitrate nitrogen in freshwater samples. The sensor uti-
lizes a polymeric membrane made with nitrate ionophore in a PVC head and a
silver/silver chloride double junction gel filled reference electrode. This sensor is
used in place of the pH sensor in the probe.
See Appendix C for details regarding the ISE sensors.
