Does the job
Used it to calibrate my 5 in 1 tester which I use to test my saltwater pool.

Two of the four bottles received leaking.
Two of the four bottles had leaked therefore two of the four were short the volume amounts.

Great value
Bought this for a pH/EC/TDS pen tester. The opening of the bottle is large enough to dip the pen directly into the solution.
