Hanna Instruments HI7074L Electrode Cleaning Solution for Inorganic Substances (500 mL)

Restore Accuracy. Protect Your pH Electrode. Maximize Performance.

The HI7074L Electrode Cleaning Solution for Inorganic Substances is a high-precision formula designed to remove mineral deposits, inorganic residues, and sample buildup that collect on pH electrodes during routine testing. Manufactured by Hanna Instruments, this specialized solution ensures your sensors stay clean, unclogged, and fully responsive—so you always get accurate, reliable pH readings.

Whether you're working in hydroponics, laboratory analysis, food testing, environmental monitoring, or industrial applications, the HI7074L is an essential maintenance product for any pH electrode exposed to inorganic contaminants.

Why the HI7074L Cleaning Solution Is Essential

✔ Removes Inorganic Build-Up for Accurate Measurement

Mineral deposits and inorganic substances can coat the electrode bulb and junction, causing unstable readings—even if the probe seems calibrated. This solution dissolves those contaminants quickly and safely, restoring proper sensor function.

✔ Prevents Clogged Junctions & Sensor Drift

A clogged junction is one of the main causes of slow response time and inaccurate measurements. Regular cleaning keeps the junction open, allowing your electrode to maintain a strong, stable mV signal.

✔ Ensures Calibration Accuracy

During calibration, your meter assumes the electrode is clean. A dirty probe leads to unreliable offset compensation and inaccurate pH readings. The HI7074L ensures your electrode is in optimal condition before each calibration session.

✔ Professional-Grade Purity & Shelf Stability

  • Air-tight, tamper-proof bottle preserves solution quality

  • Lot number & expiration date clearly marked

  • 5-year shelf life (unopened) ensures long-term reliability

Key Features

✔ Specially Formulated for Inorganic Contaminants

Designed specifically for electrodes used in solutions containing inorganic substances, ensuring maximum cleaning efficiency.

✔ Fast & Effective Routine Maintenance

Regular cleaning prevents buildup, extends electrode lifespan, and improves measurement precision.

✔ Quality-Controlled Manufacturing

Each batch is produced with strict quality standards—no Certificate of Analysis required for this model.

Why Routine Cleaning Matters

A pH meter may accept up to ±60 mV of offset, but the most accurate readings are obtained when the offset remains within ±30 mV. A dirty electrode increases this deviation, leading to false calibration and inaccurate measurements. Using HI7074L regularly prevents these issues, ensuring your electrode performs exactly as intended.
