HI 7609829-11: Chloride ion selective electrode 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. The outer body of the
sensor is the thermoplastic PEI. This sensor is used in place of the pH sensor in
the probe.
The measurement of chloride, Cl
-
is a useful tool in the measurement of surface
water contaminants such as tracing the source of roadway run off or studying
naturally occurring chloride levels in natural waters. HI 7609829-11 is an ion
selective sensor that responds to the free chloride ion. Chloride ion is the ionized
form of chlorine.
HI 7609829-11 is specified for 0.6 to 200.0 ppm (mg/L) Cl
-
. The sensor
responds in a Nernstian manner (like a pH sensor) and produces a voltage
that the meter converts to a concentration value.
