PRO6151 · technical specification HF-resistant pH composite electrode for titration applications in aggressive media
pH 2–11 0–60 °C PP sensor body Ceramic junction 3 M KCl — Designed for HF acid titration and fluoride-containing sample matrices
📋 Product Overview
Application profile
HF-containing media: intended for pH measurement in hydrofluoric acid or aggressive fluoride-containing solutions where conventional electrode materials may be rapidly attacked.
Titration workflows: suitable for analytical procedures that require electrode stability during controlled addition of titrant and endpoint tracking.
Chemical processing: applicable in metal finishing, semiconductor, glass etching support workflows and other laboratories handling fluoride-based chemistries.
Routine laboratory use: standard Φ12×120 mm format supports common titration vessels, electrode holders and bench pH meter setups.
Design and handling advantage
PP body: polypropylene construction provides chemical resistance for HF-related measurement conditions.
Composite electrode: combines pH indicator and reference electrode in one body for simpler routine handling.
Ceramic junction: stable porous junction supports consistent reference potential during titration.
S7 connector: compact detachable connector format; use an S7-BNC(Q9) cable when the meter input is BNC/Q9.
Key features
pH range: 2–11 for acidic to moderately alkaline working conditions.
Temperature range: 0–60 °C for routine laboratory titration conditions.
Reference system: Longlife reference design with 3 M KCl fill solution.
Electrode geometry: Φ12×120 mm compact laboratory format.
Matrix focus: aggressive chemical environments, especially HF acid titration and fluoride-containing samples.
Compatibility path: S7 connector directly, or S7-BNC(Q9) cable for BNC/Q9 meters.

Specification note
HF workflows: hydrofluoric-acid applications require controlled laboratory procedures, compatible vessels and trained personnel.
Connector matching: the electrode has an S7 connector; order the correct S7-BNC(Q9) cable when using standard BNC/Q9 pH meter inputs.
Method compatibility: final suitability depends on sample composition, fluoride concentration, pH range, temperature and titration method.

Configuration notice — connector and meter matching are essential

This electrode uses an S7 connector. For meters with a BNC/Q9 pH input, use an S7-BNC(Q9) cable. Confirm meter input, cable type and electrode application before purchase.

Technical values are provided for product selection and orientation. Final delivered configuration, cable, accessories and documentation should be confirmed through the official COLO.Science quotation or manufacturer-confirmed offer.

Connector and cable support
S7 electrode connector: detachable electrode connector format used on PRO6151.
S7-BNC(Q9) cable: required when the pH meter uses a standard BNC/Q9 electrode input.
BNC/Q9 meter input: common format on many laboratory pH meters; the cable creates the connection between S7 electrode and BNC meter input.
Order check: confirm whether the cable is included or should be ordered as a separate accessory.

📌 Selection and Use Notes
For HF titration
Sample matrix: verify HF concentration, fluoride content, pH range and expected endpoint conditions before selecting the electrode.
Procedure control: use only under approved laboratory SOPs for HF-containing solutions.
For meter compatibility
Connector: PRO6151 uses S7; most BNC/Q9 meters require the matching S7-BNC(Q9) cable.
ATC: this specification does not list an integrated temperature probe; use the meter's separate temperature input where required.
For documentation
Quotation: final cable, accessory and configuration details should be stated in the official offer.
Traceability: keep electrode model/SKU, cable type and meter model in the method record.
