Just a heads up.
Test reagent HI782 lot H017 expiration date 09/2026 could be bad. I have four boxes of the reagent and none work. I tested the reagent against a standard of 5 and 10 ppm NO3 made from Hach multiparameter reference standard. The developed test solutions were colorless. I tested the 5 ppm standard with the LR NO3 Checker and obtained the expected results.
I contacted Hanna technical support.
EDIT: Customer service is sending me new reagents. This issue was resolved in <8 hours!
