Replacement Electrode Checker Plus
Product Code : EL-GPA-11628
The Replacement Electrode Checker Plus is a replaceable pH electrode used to restore compatible Checker Plus pH testers for classroom and laboratory pH measurement. It is suitable for schools, colleges, chemistry laboratories, biology laboratories, laboratory technicians, science teachers, suppliers, distributors, and educational procurement buyers.
Product Description
The Replacement Electrode Checker Plus from School Equipments India is intended as a spare or maintenance electrode for compatible Checker Plus pH tester models. A dedicated indexed SEI listing for this replacement electrode was not verified, so final SKU, model reference, connector type, and supplied packaging should be confirmed before publication.
The related School Equipments India PH Tester listing confirms that the Checker Plus pH tester has a replaceable long thin pH electrode, measures from 0 to 14 pH, and provides 0.01 pH resolution. Official manufacturer information for the likely HI-1271 replacement electrode confirms compatibility with HI-98100 Checker Plus, HI-98103 pocket pH tester, and HI-98115 Groline pH Tester; confirm the exact supplied electrode before publishing.
Key Features
- Replacement pH electrode: restores compatible Checker Plus pH testers when the existing electrode is worn or damaged.
- Checker Plus compatibility: intended for compatible Checker Plus pH tester models; confirm exact model before ordering.
- Easy replacement: related documentation describes electrode replacement by unscrewing the old probe and fitting the new one.
- Laboratory pH testing support: helps maintain pH testing workflows in school and college laboratories.
- Slim electrode profile: official HI-1271 information lists a slim 8 mm polypropylene body for small vessels.
- Single-junction electrode: confirmed for the likely HI-1271 replacement electrode; verify supplied model.
- Capacity not applicable: this is a measurement sensor accessory, not a liquid-holding vessel.

How to Use the Replacement Electrode Checker Plus
- Confirm that the replacement electrode matches the exact Checker Plus pH tester model.
- Switch off the pH tester before removing the existing electrode.
- Unscrew the old electrode carefully without twisting the tester body excessively.
- Fit the new electrode into position and tighten it only as directed by the manufacturer.
- Rinse the electrode tip with suitable rinse water before calibration.
- Calibrate the pH tester using approved pH buffer solutions before measurement.
- Test a known buffer or sample to confirm stable response before routine use.
- After use, clean and store the electrode according to the recommended pH electrode storage method.
Safety note: Handle the pH electrode with care. Do not touch, scrape, dry out, drop, or expose the sensing tip to incompatible chemicals. Always use approved buffers, cleaning solutions, and storage solution for pH electrode maintenance.
Care & Maintenance
- Rinse the electrode after each use with suitable rinse water or recommended cleaner.
- Store the electrode tip hydrated using the recommended storage solution, not dry.
- Do not wipe the sensing bulb aggressively; blot gently with soft tissue if required.
- Replace the electrode if readings become unstable after cleaning, hydration, and calibration.

Frequently Asked Questions
What is the Replacement Electrode Checker Plus used for?
The Replacement Electrode Checker Plus is used to replace the pH electrode on a compatible Checker Plus pH tester when the original electrode is worn, damaged, dry, or unstable.
Is this replacement electrode compatible with every pH tester?
No. Compatibility must be confirmed against the exact pH tester model. Do not assume it fits other pH meters or pocket testers.
What is the related School Equipments India pH tester?
The related SEI product is PH Tester, Product Code EL-ME-11385, described as a Checker Plus pH tester with a replaceable long thin pH electrode.
How is the electrode replaced?
Replacement is typically done by unscrewing the old electrode and fitting the new one, but the final method should follow the instruction sheet for the exact model supplied.
Does the replacement electrode need calibration?
Yes. After fitting a new pH electrode, the pH tester should be calibrated with suitable buffer solutions before laboratory measurement.
How should a pH electrode be stored?
A pH electrode should be kept hydrated using recommended electrode storage solution. Do not store the sensing tip dry unless the manufacturer specifically allows it.
