I wish I purchased this product before wasting my money on impossible to read color tests. Well worth the money. Best upgrade I've made to date

This is soooooo much better! I really like the digital readout. The test instructions are very easy to follow.
Be careful opening the test unit for battery installation, make sure to pull the battery door out straight and do not pry it to one side.
Hanna Checker Phosphate PO4 Colorimeter By Virgil on 11/27/11

Loved this tester. No more other test for me. The digital read out makes it soo much easier. I'm getting the calcium checker for Christmas I liked this one soo much. Thanks for providing a great product. Just read the instructions and maybe review a youtube video on using it. The system has a timeout and you need to complete all the actions within a certain amount of time, but there is enough time if you are prepared.

Extremely easy to use and amazingly accurate. Absolute must for phosphate control, great to check your top-off water.

it is costly, but i am glad i got it, it is very acurate, and easy to use once you manage to dump the packet in the cuvature.

I've been using this product for a few months and the only thing I could suggest is that Hanna make a liquid reagent available. Accuracy is right on with Salifert test kit.

This is a huge step up from trying to read different shades of a color. I just can't wait till they bring out other testers
More accurate way of testing By Don on 9/29/11

This unit is as close to lab results as you can get. Just 2 simple steps and wait the 3 minutes for the results. Much easier than matching a color to a card.

I totally like having a digital read out instead of try to match colors like the other test kits, but the Hanna Checker is a little hard to use. You have to be able to open a packet with a wide opening and pour it into a very small hole, in a short amount of time. It comes with two curvettes so I started using one for the "zero" and the other for the phos reading. I still don't like the packets though, it's hard to empty all the contents without spilling reagent powder.
