Hanna Instruments HI96706C Phosphorous ISM Portable Photometer Kit

Phosphorous portable photometer kit. Kit includes photometer, 2 sample cuvettes with caps, 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case. The HI96706 uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell. This measures the phosphorus content in water samples in the 0.0 - 15.0 milligrams per liter (ppm) range. Phosphorus is found in nature as phosphates. Its concentration in water is monitored because it causes corrosion when present in high levels. It is also an essential parameter for the growth of microorganisms and algae, which are often unwanted in tanks and reserves of water. Phosphorus is also an essential element for plant growth and for this reason, is needed in large amounts. It is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.01 milligrams per liter (ppm) resolution. +/-0.03 milligrams per liter (ppm) +/-4 percent of reading at 25 degree C accuracy.
