Hanna HI50021P CAL Check solution
The Hanna HI50021P CAL Check solution is specifically designed to verify the calibration and performance of pH electrodes used with the HI-9813-6 portable pH/EC/TDS/Temperature meter. This high-quality solution is packaged in 25 single-use 20 mL sachets, offering convenience, portability, and long-term stability.
Key Features
Ensure pH Electrode Accuracy Anytime
The HI50021P solution allows users to quickly confirm whether their meter and probe remain properly calibrated. By following a simple Cal-Check™ procedure, users can determine if cleaning or recalibration is necessary—ensuring optimal performance and accuracy in the field or lab.
Convenient and Portable Single-Use Sachets
Each 20 mL sachet is sealed for freshness and clearly marked with a lot number and expiration date.
Ideal for on-site and field use thanks to its compact, disposable format.
Light-block packaging protects the solution from UV-induced oxidation.
Long Shelf Life and Certified Quality
Unopened sachets have a shelf life of up to 5 years.
Manufactured under strict ISO 3696/BS3978 standards using high-purity salts, deionized water, and certified Class A glassware.
Every batch undergoes rigorous quality checks for accuracy and consistency.
CAL-Check™ and Clean & Cal Procedure
The integrated CAL-Check™ function in compatible Hanna meters simplifies the calibration check process. Here’s how to use it:
Rinse the probe with clean water.
Immerse it in the HI50021P solution.
Press the “Check” key on your meter.
If calibration is valid, the meter shows “Probe is OK.”
If calibration has drifted, it prompts “Clean Probe and Calibrate.”
Clean the probe using a Hanna cleaning solution (e.g., HI-700661) for 5 minutes.
Rinse and recheck using the HI50021P solution.
This simple procedure ensures precise and reliable measurements every time.
