Checker your tank to make sure your parameters are on!

I meant BESIDES the price but yeah.

I'm curious because before these checkers came out, I did use a lab grade model of refractometer for phosphate from Hanna, but it was a much different looking unit than the one pictured. The lab grade unit still had a precision of 0.01 but with an accuracy of plus/minus 0.04, which IIRC, is the same for the handhelds. So the nice thing about the handhelds is that they have theoretically the same functionality to the same degree but at a much smaller price.

But I'm still curious about this white model refractometer as it is not the same as what I had before. I was wondering if it might be a multitester in that it's capable of "refractometerifying" different stuff. I'm kind of guessing not, but I'm still going to ask the question nonetheless.
