YSI Nitrogen, Ammonia HR, Vial Reagent neo Quick reference guide and factoryNitrogen, Ammonia HR (high range) vial reagent, for up to 49 tests. Range: 0. 4 50 mg L NH4 N or 0. 5 64. 4 mg L NH4. NH3 N and NH3 can be calculated with pHotoFlex pH and a connected pH temp external probe (range is temperature and pH dependent). pHotoFlex STD can calculate NH3 via multiplier.
