Description
The GF Amperometric Chlorine Electrodes is designed for use in fresh,
clean water treatment applications where a level of Chlorine is always detectable.
Free Chlorine electrodes are available in measurement ranges of 0.02 to 2 ppm,
0.05 to 5 ppm or 0.1 to 20 ppm.
Chlorine Dioxide electrodes are available in measurement ranges of 0.02 to 2 ppm.
Electrodes require the 2650 Amperometric Electronics to output a digital (S
the 9950-3 Chlorine Controller.
Features:
•
Utilizing smart-sensor technology, this electrode incorporates a unique
embedded memory chip within the electrode to communicate a wide variety
of information to the 2650 Amperometric Electronics and 9950-3 Chlorine
Controller. Electrode type, factory calibration data, service time, chlorine range,
high and low temperature and more are stored on the chip. This information is
accessible via the 9950-3 Chlorine
•
GF's patented DryLoc
®
connection. Gold-plated contacts and an O-ring seal ensure a waterproof and
reliable interconnect to the 2650 Amperometric Electronics.
•
Integrated temperature element for automatic temperature compensation.
•
Separate drive electronics (2650) allow easy electrode replacement without
running new cable.
CAUTION!
1. Follow instructions carefully to avoid personal injury or damage to electrode.
2. Prior to installation or removal:
a. Disconnect fl ow through system.
b. Drain below sensor level.
3. Confi rm chemical compatibility before use.
4. Do not exceed the maximum pressure or temperature specifi cations.
5. Do not alter product construction.
WARNING:
The GF Chlorine Analyzer (electrode) is designed to be used in a
clean, chlorinated fl owing stream at all times. DO NOT use in applications where
electrode could be exposed to periods without chlorine.

Page 10: Overview
Chlorine Measurement by Amperometric Sensors GF chlorine sensors are membrane-covered amperometric 2-electrode sensors. A gold or platinum cathode acts as the working electrode with a silver halide acting as the counter electrode. Depending on the species to be analyzed, a polarization voltage is applied between the two electrodes. -
