PRO6237 Combined Fluoride Ion Selective Electrode
PRO6237 combined fluoride ion selective electrode is an ISE probe for fluoride ion F– measurement with compatible ion meters and ISE-capable electrochemistry meters. The combined electrode design integrates the measuring electrode and reference electrode function in one probe body, simplifying routine fluoride ISE measurement compared with separate ISE and reference-electrode setups. PRO6237 uses a crystalline-state membrane, plastic body and BNC(Q9) connector.

ISE measurement methods and combined-electrode system compatibility
ISE measurement modes
PRO6237 can be used in ISE workflows such as Auto-reading, Standard Add, Sample Add and GRAN methods when these functions are available on the connected ion meter or electrochemistry meter.
Combined ISE design
The combined ISE probe integrates the reference electrode function, reducing the need for a separate external reference electrode in routine fluoride ion measurement setups.
Connector compatibility
The connector must match the meter input. PRO6237 is specified with BNC(Q9). If an S7 electrode/cable configuration is required, an S7-BNC(Q9) cable should be confirmed before delivery.

Applications and laboratory value
Water quality laboratories
The PRO6237 combined fluoride ion selective electrode is suitable for fluoride ion measurement in water quality workflows when paired with a compatible ISE meter and method setup.
Environmental analysis
The electrode can support fluoride ISE measurement in environmental sample workflows where the sample matrix, standards and ionic-strength conditions are controlled by the selected method.
Education and research
PRO6237 is useful for teaching ISE theory, ion activity measurement, calibration practice and addition-method workflows in electrochemistry laboratories.
Routine QA/QC
A combined fluoride ISE electrode helps laboratories simplify probe setup while maintaining a clearly defined fluoride measurement configuration for routine testing.
How to choose the correct combined fluoride ISE configuration
When selecting the PRO6237 combined fluoride ion selective electrode, the complete measurement system should be checked, not only the electrode body. The final configuration should include a compatible ISE-capable meter, the correct connector or cable, suitable standards and any sample-preparation requirements defined by the laboratory method.
COLO.Science can support selection of the combined fluoride ISE electrode, cable configuration, standards and accessories so that the final measurement setup matches the meter input and the expected fluoride concentration range.
PRO6237 combined fluoride ion selective electrode for practical fluoride measurement
The PRO6237 combined fluoride ion selective electrode is a practical electrode choice for laboratories that need a dedicated fluoride ISE probe with integrated reference function and BNC(Q9) connection. Its specified 10-1 M to 10-6 M measurement range makes it suitable for a wide range of fluoride ion measurement tasks when the method and sample matrix are correctly controlled.
In practice, fluoride ISE measurement quality depends on the full analytical workflow: electrode condition, standards, sample preparation, meter functions and temperature conditions. PRO6237 provides the combined measuring electrode, while the final measurement set should be configured as a complete system before quotation and delivery.
