Please note!
This link sells A powder and B powder for the preparation of an oxygen-free water dissolved oxygen meter. The rest of the picture is only used as a demonstration mold and is not included.

Please note! Product upgrade!

The powder of JPB-70A will only have 5 packs of A powder in the future, no need for B powder.
Reasons for improvement:
A pack of A and B each with anaerobic water can only be used on the same day, now A pack of A plus water is poured into the bottle; A pack of A can be used for one month, 5 packs can be used for 5 months

Previous products can also use only A powder
