I just bought a API test kit from my LPS but I'm not sure when it expires. Can somebody please let me know how to figure this out.

I have had some for years and then compared them to brand new ones and they were still right on. As a rule of thumb people say replace your kits every year, but I personally think that is overkill.

API says they are only acurate up to 3 yrs and after that they will give you a low reading. I had some that were 6 yrs old and called them to find out about their shelf life. On every bottle there is a lot number and the last for digits are the date it was made i.e. 27A0107
