Excellent!

Comments: Easy to use, and accurate glad to have this makes checking your calcium levels alot quicker than the standard reef drop tester and wish I would have bought this productsooner. Thanks to all the help from the techs will do business with you again you guys are scholars and listen to what customers want not just sell you something you don't need.

Easy to use Product Review by GERAUD KRAWEZIK (Posted on 2/26/14)

Great!

Comments: Easy to use and fast. You just need to make sure the regent package is opened while the unit is zeroing rather than waiting till it is waiting for you to pour.

Since the unit automatically shuts down shortly after taking a measures, it would be great if it would beep to signal when it can be read.

Excellent!

Comments: I have put off buying one of the Hannah Checkers but as I am testing ALK a lot right now to try to dial in my dosing pumps I thought now is the time. And I am glad I did! Accuracy is great when I compared to my Red Sea ALk Pro test kit. Makes testing much faster and easier!
