Hanna Instruments HI3824 Ammonia test kit 0.0-2.5 mg/L


Hanna Instruments ammonia test kit HI3824 for fresh water. This kit measures ammonia - nitrogen (NH3-N) in the range 0.0-2.5 mg/L in steps of 0.5 mg/L. The kit can perform approx 25 tests. High levels of ammonia in water usually indicate inability of the system to deal with organic matter load. Under low oxygen conditions ammonification produces ammonia compared to aerobic decomposition that progresses to nitrate. The proportion of ammonium to ammonia is pH and temperature dependent. In acidic (less than pH 7) solutions less harmful ammonium dominates but as pH rises harmful ammonia levels increase.

At 20 deg C here is the proportion (%) that harmful ammonia makes up of the total ammonia and ammonium: pH 7, 0.4%; pH 7.5, 0.99%; pH 8, 3.83%. Source Lamotte Smart Colorimeter Manual. So take a pH reading when measuring ammonia-N then multiply by the percentage given (interpolate if necessary) to get harmful ammonia.
