I purchased a DKH certified standard kit about 8 months ago by accident instead of reagents and this morning I tried to check my hanna 772 with them.
I'm getting a reading of 6.0-6.1 and I dont understand the reading I'm getting vs. The certificate acceptable results between 90 and 110ppm.

Some help pls, tyvm!
