Hanna HI7021L 240 mV ORP Test Solution – 500 mL

The Hanna HI7021L is a high-purity, laboratory-grade 240 mV ORP test solution. Packaged in a UV-blocking 500 mL bottle, it provides a stable reference measurement of 240 mV (@25°C). It is utilized to condition and verify the operational integrity of ORP and REDOX electrodes, ensuring precise measurements in food processing, wastewater, and advanced agricultural diagnostics.

Validate your low-range oxidation diagnostics with the Hanna HI7021L 240 mV ORP Test Solution. While massive municipal water plants deal with high ORP values (using 470 mV test solutions), many specific chemical reactions in Pakistan’s food processing, wine/beverage fermentation, and anaerobic wastewater treatment sectors require tracking much lower oxidation-reduction states.

The HI7021L provides the exact chemical baseline required to test sensors operating in these sensitive environments. By submerging your cleaned ORP electrode into a sample of this solution, the meter must return a reading of 240 mV (@25°C). This immediate diagnostic test allows QA technicians to confirm that the platinum or gold sensing ring is free from protein fouling and electrical degradation. Supplied in a heavy-duty 500 mL Light-Block Bottle, it guarantees your industrial sensors are always reading the truth.

Key Features:

• Low-Range Verification: Provides a specific 240 mV baseline required for testing ORP electrodes used in anaerobic and food-science applications.
• Sensor Conditioning: Can be used to condition the metallic sensing ring before critical chemical titrations.
• Air-Tight Seal: Manufactured with a tamper-proof, air-tight seal to ensure absolute chemical stability during long-term storage in hot factories.
• GLP Compliant Labeling: Features comprehensive temperature/mV reference charts printed directly on the bottle for quick cross-referencing.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI7021L in Pakistan?

A: Check Kamadi.pk for competitive B2B rates. We support commercial testing laboratories with fresh, authentic Hanna reagents.

Q: HI7021L vs HI7022L: Which ORP solution do I need?

A: Both test the health of the electrode, just at different voltage targets. If you generally measure highly oxidative water (like chlorinated swimming pools >600 mV), use the HI7022L (470 mV). If you measure lower-range industrial reactions, use the HI7021L (240 mV).

Q: Does temperature affect the reading?

A: Yes. The solution is exactly 240 mV at 25°C. The bottle includes a printed chart showing the exact expected mV reading if your testing room is hotter or colder than 25°C.
