Hanna Instruments HI96713 Low Range Phosphate Portable Photometer with Sample Cuvettes, 7-19/32" Length x 4-3/32" Width x 2-11/16" Height, 0.00 - 2.50mg/L, 0.01mg/L Resolution, 9V Battery
Phosphates are particularly important for the growth and development of plant roots, and hence are one of the most common fertilizers used in agriculture. Phosphates are also utilized in detergents and are needed, in small quantities, for heating systems. However, high concentrations of phosphates can cause environmental pollution as they are a primary cause of eutrophication. For these reasons, it is necessary to closely monitor the phosphate levels present in both municipal and industrial waste water. The HI96713 measures phosphate content in water, wastewater and seawater in the 0.00 - 2.50 milligrams per liter (ppm) range. 0.00 - 2.50 milligrams per liter range. 0.01 milligrams per liter resolution. +/-0.04 milligrams per liter +/-4 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 610nm light detector. Adaptation of the ascorbic acid method. 0 To 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. 9V Battery. auto-shut off: after ten minutes of non-use in measuring mode after one hour of non-use in calibration mode with last reading reminder. Measures 7.6" length by 4.1" width by 2.7" height.
