+1 that's what I got.There are 20drops per mL, I weighed the NP pro and it weighs 0.048g per drop(Close enough to the standard of 0.050g/drop for water)
So for a 50ML bottle there are 1000drops.
2L of NP Pro for dosing pumps at 5ml/100L dose volume has 400 doses.
So unless Im missing something you need 20mL concentrated NP Pro mixed into 2L of DI water.
Matt what test kit are you using for K?
