pH / ORP Electrode Solutions
HANNA Instruments solutions are prepared from precise formulas and are measured against NIST standards.
Each label carries the Lot Number, Expiry Date and pH accuracy at specific temperatures.
The solutions can also be delivered with an optional Certificate of Analysis.
The Certificate of Analysis must be ordered when ordering the solution.
These solutions are available in 500 mL plastic bottles.
Other sizes are available. Please contact us for availability.

Cleaning Solutions
The precision and life span of a pH or ORP electrode is directly connected to their maintenance and use.
We strongly recommend frequent cleaning of the electrode with the appropriate solution (at least once per week). These solutions are available in 460 mL plastic bottles. Other sizes are available. Please contact us for availability.
It is highly recommended that the electrode be immersed in the storage solution when not in use.
