Hello,
I have used your product for years and I am now finding an issue with new reagents. I used up my old reagent and opened up a new box. Instantly the results were different and I did not think much of this until the problem started. Now that I had a tank issue this is what i am finding. I have used two new regent solutions and those test are consistent with each other however when I test on Salferit test kits. new box and old box i get completely different readings from what my checker says. the difference to me is huge as it is 1.3 DKH. I don't know what test is right or wrong. I have now ordered brand C to compare but something here is wrong. Are there any bad batches on your end that I may have in my hands. In the past my Hanna and Salferit test were always pretty close.
Thanks for your help
