Compatibility and use notes
| Topic | Technical note |
| Meter input | Requires compatible S7 connection or S7-BNC(Q9) cable for pH meters with BNC input. |
| Temperature compensation | This is a pH electrode. Temperature compensation depends on the connected meter and separate temperature probe configuration. |
| Calibration | Calibrate with fresh pH buffers according to the laboratory method, expected pH range and sample temperature. |
| Handling | Use care with the long glass body. Avoid side impact, bending stress and contact with hard vessel walls. |
| Storage | Store and clean according to the applicable laboratory method and electrode storage guidance. |
Product selection table
| Selection item | Specification / guidance |

Specification note
Connector matching: confirm whether the meter requires S7, BNC(Q9) or an S7-BNC(Q9) cable before ordering.
Long electrode handling: use stable holders and avoid mechanical stress on the glass shaft.
Immersion depth: ensure the sensing end and junction are correctly immersed in the sample zone.
Quotation control: final supplied configuration, cable, accessories and documentation should be confirmed in the official COLO.Science quotation.
Technical values are provided for product selection and orientation. Final delivered configuration, electrode type, accessory set, connector/cable arrangement and documentation should be confirmed through the official COLO.Science quotation or manufacturer-confirmed offer.
