Hanna Instruments HI96700C Low Range Ammonia Portable Photometer Kit

Low range ammonia portable photometer kit. Kit includes 2 sample cuvettes with caps, 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case. The HI 96702 meter measures the copper content in water and wastewater. These meters use an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell. 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, portable water, boiler feed water, sewage, industrial and waste water. 0.00 To 3.00 milligrams per liter (ppm) range. 0.01 milligrams per liter (ppm) resolution. +/-0.04 milligrams per liter (ppm) +/-4 percent of reading at 25 degree C accuracy.
