Store the reagent in the fridge and shake before each use.

Here's the correspondence I had with this topic.
Hope it helps

I have had the same issue with the different readings. I am a Hanna dealer and asked my sales rep about it. He said they are not interchangable. So idk what the real answer is, but I stick with the right reagent for each checker. The best way to get the correct one is to order direct from the Hanna Instruments website.

Whoever told you that is wrong.

If it was Hanna, please let me know their by name by PM so I can discuss direct with Hanna management.

The reagent is the same, only the part number is different.

The difference is probably because the old bottled was not refrigerated.

Where does it say the bottles have to be refrigerated?

I think some people may have had better results refrigerating the reagent, and it is not a requirement. I don't myself, but I do swirl the reagent to gently mix it prior to each use. I try not to foam it up with air. I usually get consistent results using the correct reagent. Is it because of swirling, idk, but just a habit of mine.

Ahh ok, I give the bottle a swirl also before use.
