How long before a Test Kit expires?


Active member
mine all have "best if used by" dates on them - when in doubt, throw 'em out!!!

An inaccurate test is at least as bad as no test at all. If you doubt a result, get either a new test kit or another brand, or both

Most gurus would suggest 1 year from date of purchase. Write the expiry on the side with a black marker so you won't forget.

And...kits exposed to heat and humidity will go sooner than those in ideal conditions.

You can always test your #'s against another reefers kits to see. Not a bad practice even with non-expired test kits.
