1. Description
The Signet Amperometric Chlorine Electrodes are designed to measure chlorine in fresh, clean water treatment applications.
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 Signet 2650 Amperometric Electronics to output a digital (S
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. Sensor Preparation
• Chlorine sensors are shipped without internal electrolyte solution.
• Prior to installation and supplying power, Chlorine sensors must be fi lled with the appropriate internal electrolyte solution.
• Verify the correct electrolyte solution is utilized with the corresponding sensor.
• Free Chlorine and Chlorine Dioxide sensor require different electrolyte solutions.
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.
CAUTION: DO NOT touch the gold tip or the membrane of the sensor.
Initial Fill Procedure:
When adding electrolyte, be prepared for an accidental spill.
Working near a sink is recommended.
Remove the protective bottle from the end of the electrode
1.
Remove the membrane cap from the front of the sensor.
2.
Note: When new sensors are shipped, the membrane cap is not tightened to the sensor
Fill supplied syringe with electrolyte solution.
3.
Place the electrode on a level surface.
4.
Insert syringe needle fully into one of the eight electrode holes while injecting with
5.
electrolyte solution. Slowly injecting the electrolyte solution into the sensor to avoid
introducing air bubbles. The electrode holds approximately 14 milliliters of solution.
Slowly fi ll until solution begins to fl ow out of holes. Do not allow the solution to run
down the electrode and wet the electrical contacts in the DryLoc connector.
Slowly screw on the membrane cap fi nger tight. Do not use tools.
6.
To avoid damage and contamination, do not touch the white membrane surface on
the membrane cap.
