Hanna Checker Phosphate Calorimeter Review?

[Nandez13]

For those that have used the hanna checker phosphate calorimeter, how have you liked it? I'm referring to this one:

I'm currently using an API test kit, so obviously it would be a step up but I wanted to see how it compares to the units that are closer to the $200 range. For this price, it doesn't seem like a bad deal. How accurate is it if you've done a side by side test to the more expensive ones?

They work well. You can get it bought and shipped cheaper and faster on amazon.

I like the hanna checker colormeter. I found that you have to make sure the glass vial is clean of finger prints, lint and evaporating saltwater. I rinse the outside with 0 TDS water to remove any saltwater, then I use a micro fiber cloth to polish it before starting the test procedure. Then I give it a quick wipe before dropping it in for the final reading.

I guess you get what you pay for. Even though I've read several positive reviews on it, it seems that people are more pleased with the price they got it for. I don't have an SPS dominant tank so I can get away with having low levels of PO4 (as opposed to 0) for now. I'm not overrun with algae so I'll take solace in that for now.

Gna keep my eyes open for anyone selling a higher quality used one on here.

I used that Hanna Checker but switched to the ULR Phosphate Checker for the same price. It gives more precise reading.
A minor drawback is you have to convert your result.
The good news is it's an easy calculation. multiply your result by 3 and divide by 1000.
I just tested my water and got a result of 15 which works out to .045 ppm.

I don't bother converting anymore since its the only thing I use now, Just try to keep it close to or below 10 for SPS. The ULR is definitely more precise than the regular Hanna Checker.

Good to know. I'll have to look into that one. The conversion seems like a minor inconvenience if it's more accurate and still the same price
