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

3

L) signal to 

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 Controller

.

• 

GF's patented DryLoc

®

 connector provides quick assembly and a secure 

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.

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.
