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-X 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-X 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-X 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.
* NOTE: The 9950-X Chlorine Controller is not compatible with the standard
9950 controller.
CAUTION!
1. Follow instructions carefully to avoid personal injury or damage to electrode.
2. Prior to installation or removal:
a. Disconnect flow through system.
b. Drain below sensor level.
3. Confirm chemical compatibility before use.
4. Do not exceed the maximum pressure or temperature specifications.
5. Do not alter product construction.
WARNING:
The GF Chlorine Analyzer (electrode) is designed to be used in a
clean, chlorinated flowing stream at all times. DO NOT use in applications where
electrode could be exposed to periods without chlorine.

Page 4: Sensor Preparation
Sensor Preparation • Chlorine sensors are shipped without internal electrolyte solution. • Prior to installation and supplying power, Chlorine sensors must be filled with the appropriate internal electrolyte solution. • Verify the correct electrolyte solution is utilized with the corresponding sensor. • Free Chlorine and Chlorine Dioxide sensors require different electrolyte solutions. Avoid skin or eye contact with electrolyte solution. Wear rubber gloves and goggles. -

Operation Electrode Range: The electrode must match the type and range of Part Number Chlorine Range Chlorine Type chlorine concentration to be measured. 3-2630-1 0.02 to 2 ppm (mg/L) Flow Rate: 3-2630-2 0.05 to 5 ppm (mg/L) Free Chlorine The electrode must have a stable and constant flow of water past its 3-2630-3 0.1 to 20 ppm (mg/L) membrane for accurate measurement. -
Page 6: Maintenance
Maintenance Verifying the sensor's accuracy using the DPD method should be performed to determine if the sensor requires maintenance. Inspect the membrane for dirt or damage. Replace the membrane if it's torn or if the gold cathode is visible. If the membrane is dirty clean the membrane by soaking it in 1 - 5% HCL and gently wash with a stream of DI water. (do not use any mechanical device on the membrane) Diluted HCl can irritate the eyes and skin, use proper safety equipment. -
Page 7: Storage
Storage Dry electrodes are shipped and need to be stored between –10 ºC to 60 ºC (14 ºF to 140 ºF) at a relative humidity that does not exceed 95%.The primary concerns when storing the electrode is damage to the membrane. DO NOT FREEZE If the sensor or panel assembly is to be removed from service for a period of time the sensor must be properly prepared for storage... -

Page 10: Overview
Overview Chlorine in Water Various forms of chlorine are used to disinfect water. Each form of chlorine has benefits and limitations which help determine the specific application. The predominant categories used in disinfection are Free Chlorine, Total Chlorine and Chlorine Dioxide. Free Chlorine is the sum of chlorine gas (Cl ), hypochlorous acid (HOCl) and hypochlorite (OCl ). Above pH 4.0 all of the molecular chlorine is converted to HOCl and OCl . Hypochlorous acid is a more potent disinfectant than hypochlorite and exists in a pH dependent equilibrium as shown in Figure 3. -
