1. Description
Signet's Amperometric Chlorine Electrode is designed to measure free chlorine in fresh water and waste water treatment
applications. The electrode is available in measurement ranges of 0 to 2 ppm, 0 to 5 ppm or 0 to 20 ppm.
This electrode requires the Signet 2650 Amperometric Electronics module to output a digital (S
Chlorine Transmitter.
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 Signet 2650 electronics and Signet 8630 transmitter. Electrode type,
factory calibration data, service time, chlorine range, high and low pH (with optional Signet pH electrode), temperature limits
and more are stored on the chip. This information is accessible via the Signet 8630 transmitter.
• Signet's patented DryLoc
seal ensure a waterproof and reliable interconnect to the Signet 2650 Amperometric Electronics.
• Integrated temperature element for automatic temperature compensation.
• Separate drive electronics (Signet 2650) allow easy electrode replacement without running new cable.
2. Electrolyte
Avoid skin or eye contact with electrolyte solution.
Wear rubber gloves and goggles.
* Material Safety Data Sheets (MSDS) are available online at
www.gfsignet.com.
• Free chlorine electrodes are pre-filled with electrolyte solution. Simply pull off the
protective boot from the end of the electrode and install the electrode into the flow
cell fitting.
• The membrane cap must be replaced every time the electrolyte is changed.
Fill and Refill Procedure:
When adding electrolyte, be prepared for an accidental spill.
Working near a sink is recommended.
1. Remove the membrane cap from the front of the sensor.
2. Turn the sensor upside down and shake the sensor vigorously to remove the
internal electrolyte.
3. Fill supplied syringe with electrolyte solution.
4. Place the electrode on a level surface.
5. Insert syringe needle fully into one of the four electrode holes while injecting
with electrolyte solution. The electrode holds approximately 14 milliliters of
solution. Insert the needle to the bottom to avoid creating bubbles. Carefully fill
until solution begins to flow out of holes. Do not allow the solution to run down
the electrode and wet the electrical contacts in the DryLoc connector.
6. Slowly screw on the membrane cap finger tight. Do not use tools.
To avoid damage and contamination, do not touch the white membrane surface
on the membrane cap.
