Product Questions

Does this also work with the HR 782 as I don't see a calibration set on your site for the HR Nitrate checker. Can you also get the 100 reagent packs skewed up for the HR as well as the 713 ULR checker so we don't have to wait for the 25 packs to be in stock? Hanna has both readily available. Thx

Hey there,
Thank you for reaching out to us. Unfortunately, it will not work with the HR-782. I will bring up the request for the 100 pack with the new product team.

Please let me know if you need anything further and take care!

Does the checker have a calibration adjustment setting? If the reference solution yields a different number on my checker than expected, how do you make the calibration adjustment?
Question by: Robert Barrow on Nov 10, 2021, 2:21 PM
It does not, the calibration solution is just to ensure the checker is reading properly.
