Yes the checker comes with reagents for about 25 tests.
Still reads much lower than Salfert.
Even with the 5ppm error range in the Hanna. I can not make heads or tails on this.
I am sorry to hear about the differences in your test kit. We have had great luck with hanna in the past and certainly have used their products and standards regularly. At this point we recommend reaching out to hanna to ensure the checker is up to par and functioning correctly with the use of standards or other re-calibrating effects.

Great Product By Joseph on 1/15/2017Joseph would recommend this product to a friendThis product takes the pain out of testing manually. Loved it!
Digital Results By jag909 on 10/31/2016jag909 would recommend this product to a friendNo Guessing, digital readout, i am sold! Great to have a definite number to go with the results.
So much better. By TrentN on 7/26/2016TrentN wouldn't recommend this product to a friendNow this it a tester I like. the only way it could be easier would be if it was a probe. I made the mistake of ordering the ppm tester when I wanted the dKH one, but in the package has a sheet that has the multiplier to go from ppm to dKH so no biggy.
Pluses and Minuses By John on 5/16/2016John would recommend this product to a friendPluses - Easy and fun to use, which means I'm testing more; it's accurate.
Minuses - You have to manually do the conversion to DKH or meq/L, which seems odd for an electronic device. The box is comes in is funky and not designed well. It's not as fast as some say, but still easier and faster than a Red Sea type tester. The instruction manual is simple to understand, but a little weak on information.
The best…..when it works By Mcmullen on 4/8/2016Mcmullen wouldn't recommend this product to a friendSo this is easily the best Alk checker when Hannah has their reagent working properly. Sometime in Novemeber 2015 (maybe sooner) they changed packaging so that when the liquid reagent encounters the bottle lid, it somehow deactivates the reagent. This was addressed, and supposedly fixed! Well, guess what? Still same problem!! I finally ordered a "Salifert" kit and my Alk level tested higher than the max level…..the max is 15.8! I kept dosing Alk based on my Hannah reading low levels. For those of you that do not know, anything higher than 12 is high for Alk, and my tank runs about 9. This is a sps killer. I do believe Hannah will fix the problem but how can you trust the product. I'll constantly be double checking!! I cannot recommend at this time!!!
Excellent and easy to read. By DAVID on 4/3/2016DAVID would recommend this product to a friendI find this one easier than API or Red Sea to read. I just made a ALK Table with the reading and dkh. So all I have to do is look at my chart.
SUPER EASY TO USE! By TWang on 3/1/2016TWang would recommend this product to a friendThis is very easy to use and is accurate. Kind of pricey but well worth it.
great product By Jason on 1/25/2016Jason would recommend this product to a friendSuper easy and always accurate.
No more guessing color. By Reefdoc on 1/16/2016Reefdoc would recommend this product to a friendWorks great! Takes the guess work out of alkalinity testing. This is my first hanna checker and now I'm going to be replacing my other testing slowly with Hanna checkers.
Easy and Precise By John on 1/16/2016John would recommend this product to a friendI had been using the Red Sea Foundations test kit, which I think are one of the better test kits, but this Hanna Checker is fantastic. It is very easy and I love the precise reading. I also bought the Calcium checker.
Easy to use just follow instructions By Jeff on 1/13/2016Jeff would recommend this product to a friendI am trying to be a much better aquarium keeper starting this year 2016. Had my water tested and both alkalinity and PH were low. using a Reef Buffer 8.3 to raise the PH and Alkalinity and this meter help to know parameters so that you don't shock the fish as your trying. Much better then counting drops like the other testers.
Great product and easy to use By jsbull on 1/2/2016jsbull would recommend this product to a friendYou put tank water in the vial and push the button. Then add 1ml of regent, invert the vial a couple of times and push the button again. Can't be easier and it does give more exact results than the API style test kits.
