Using expired calibration fluid?

[cvrle1]

I have purchased 3 pack of Milwaukee M10080 TDS Calibration Fluid, and 1 of the 3 packs that came expired in April 2019. I will get partial refund for it, but want to know if calibration fluid is still good to use, or should I toss this one packet?

Thanks for the help.

I wouldn’t trust it, they put expiration dates on there for a reason.. if it was just a few week out it would probably be ok but 6 months is another story.

Thanks, thats what I was thinking as well, but wanted to check. I thought it may be like putting expiration on table salt sort of a thing
