Horiba ABX Pentra Reference Electrode (ISE) – Pentra 400 / C400 (P/N 3014029451)

What is it:

The Horiba ABX Pentra Reference Electrode is a genuine HORIBA Ion-Selective Electrode (ISE) for the ABX Pentra 400 / Pentra C400 clinical chemistry analyzer. It's the reference electrode for the analyzer's ISE module, supplied ready-to-use as a single electrode.

Part numbers:

• Catalog P/N: 3014029451
• Box REF: A11A01741

What it's used for:

The reference electrode provides the stable baseline voltage the Pentra 400's ISE module measures against to report electrolytes. The module determines Sodium, Potassium, and Chloride by potentiometry — it reads the electrical potential between this reference electrode (bathed in reference solution) and each ion-selective electrode (bathed in sample). Because every electrolyte result depends on that baseline, a worn or failed reference electrode can throw off all Na/K/Cl readings. As a consumable with a finite service life, it's replaced periodically to keep the ISE module accurate.

What's included:

• 1 × ABX Pentra Reference Electrode (ISE), ready-to-use
• Catalog P/N: 3014029451 · Box REF: A11A01741
• Genuine HORIBA service part
• For the ISE module of the Pentra 400 / Pentra C400 analyzer

Compatible analyzer:

• ABX Pentra 400 (Pentra C400) Clinical Chemistry Analyzer (ISE module)

This is the reference electrode — one of four electrodes in the Pentra 400 ISE module. The others are the Sodium (3014029448), Potassium (3014029450), and Chloride (3014029449) electrodes, each a separate part. Order the specific electrode you need. Not for use with non-HORIBA instruments.

FAQs:

What is the Horiba ABX Pentra Reference Electrode used for?

It's the reference electrode for the Pentra 400 / C400 ISE module. It provides the stable baseline voltage the module measures against to determine Sodium, Potassium, and Chloride by potentiometry. Every electrolyte result depends on it.

Which analyzer is P/N 3014029451 compatible with?

The HORIBA ABX Pentra 400 / Pentra C400 clinical chemistry analyzer, specifically its ISE (Ion-Selective Electrode) module.

How is the reference electrode different from the Sodium, Potassium, and Chloride electrodes?

The ISE module uses four electrodes. The Sodium (3014029448), Potassium (3014029450), and Chloride (3014029449) electrodes each measure their specific ion; the reference electrode (3014029451) provides the baseline they're all measured against. They're separate parts — order the one you need.

Does it need refrigeration?

No. Store at room temperature, 15–35°C, per the label.

How do I know when to replace it?

ISE electrodes have a finite service life and degrade with use. Signs include ISE calibration failures, drifting or out-of-range Na/K/Cl results, and reference-related error codes. Follow your Pentra 400 ISE maintenance schedule, and replace the reference electrode when calibration or QC indicates it's at end of life.

What's the difference between the box REF and the catalog number?

The unit label shows REF A11A01741; distributors order it as P/N 3014029451. They're the same product — we list both so you find this page whether you're matching the box in your hand or your last invoice.
