Sensor Preparation
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.
Initial Fill Procedure:
When adding electrolyte, be prepared for an accidental spill.
Working near a sink is recommended.
1. Remove the protective bottle from the end of the electrode
2. Remove the membrane cap from the front of the sensor.
Note: When new sensors are shipped, the membrane cap is not tightened to the sensor
3. Fill supplied syringe with electrolyte solution.
Additional caution should be taken when handling Chlorine Dioxide electrolyte solution.
4. Place the electrode on a level surface.
5. Insert syringe needle fully into one of the eight electrode holes while injecting with
electrolyte solution. Slowly injecting the electrolyte solution into the sensor to avoid
introducing air bubbles. The electrode holds approximately 14 milliliters of solution.
Slowly ¿ ll until solution begins to À ow 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 ¿ nger tight. Do not use tools. To avoid damage
and contamination, do not touch the white membrane surface on the membrane cap.
• Chlorine sensors are shipped without internal electrolyte solution.
• Prior to installation and supplying power, Chlorine sensors must be ¿ 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.

NOTE: Inspect and change the
membrane cap if damaged.
See page 36, Maintenance, for
cleaning procedure.
A new chlorine electrode or one that has had the membrane cap changed must be
calibrated. See page 24, 8630 Transmitter information on calibration of the chlorine
sensor. A diethyl-p-phenylenediamine (DPD) colorimeter test kit (not included) is required
for sensor calibration. A sample is taken and analyzed with the DPD test kit, then this
value is entered into the Signet 8630 transmitter.
• Calibrate after a membrane cap change (requires 4 hour stabilization time).
• Calibrate after the internal electrolyte is replaced (requires 2 hour stabilization time).
• Check calibration one day after sensor is placed in service.
• Check calibration weekly to monthly depending on process requirements.
The sensor membrane and internal electrolyte solution must be replaced over the life
of the electrode. To maintain accurate chlorine measurements, GF Signet recommends
that the internal electrolyte be replaced every 3 to 6 months, or when Chlorine readings
drift low and/or cannot maintain a calibration longer than 5 days. Actual interval between
maintenance of the sensor will be dependent on the actual applications, chlorine level and
contaminates in the water. See Appendix page 36; Maintenance and Storage.
Keep spare membrane caps available. Membrane caps carry no warranty.
