Question
Is Hach currently exploring EPA approval for SL1000 Portable Parallel Analyzer™ (PPA) methods other than Chlorine?
Summary
EPA approval, SL1000
Answer
At this time we are not pursuing further EPA approvals. We are considering potential approvals for Nitrite and Free Ammonia in the future but have not begun the process at this time due to a lack of demand for approved methods outside of Chlorine.
