Ammonia is often an excellent indication of the presence of animal or plant microbiological decay. It is tested in fish farms (fresh and salt water tanks) due to the damaging effects of its toxic nature. Its presence in rivers and reservoirs normally points to agricultural and/or civil pollutants. Ammonia is tested in lakes, rivers, potable water, boiler feed water, sewage, industrial and waste water. The HI-93700 measures from 0.00 to 3.00 mg/L.
The HI-93700 is supplied complete with 2 cuvets, battery and instructions.
