  • Not very useful By DBR_reef on 5/24/2017

    Great if you want to test the accuracy of your colorimeter, but considering the error in the Hanna dkh checker is almost always in the reagent (which this does not test for), this is not very useful. I've had the dkh be off by more than 1 dkh between reagent batches, but this won't help with that.
  • Easy to use By John on 4/9/2017

    I got this product to check my Hanna PO4 checker... I got a result of 11.1 with a liquid test kit and ny checker showed a KH of 9.8... somebody was lying. So the Hanna control sample arrived which has a confirmed Kh of 5.0. I tested it in the checker and it registered 5.1... pretty impressive. So now I'm trusting that vs the liquid test (PS.. The liquid test kit had expiration date of 2018 btw so it was new)
