Potassium as a chemical element is commonly found in nature. It is present in soil and drinking water and is also an essential element for the growth of plants and animals. Potassium concentration is important in determining the quality of soil in many greenhouse, agriculture and horticulture applications. Potassium salts are also a common component of fertilizers. The HI96750 measures the potassium (K) content in water samples in the 0.0 to 10.0 milligrams per liter (ppm) for low range and 10 to 100 milligrams per liter (ppm) for medium range. The HI 96750 uses the Tetraphenylborate Method. The reaction between potassium and reagents causes turbidity in the sample. HI96750 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. 0.0 to 10.0 milligrams per liter LR and 10 to 100 milligrams per liter MR range, 0.1 milligrams per liter LR and 1 milligrams per liter MR resolution. +/-1.5 milligrams per liter +/-7 percent of reading at 25 degree C accuracy. Light emitting diode. Silicon photocell with narrow band interference filter at 466nm light detector. Battery Type / Life: Approximately 40 hours of continuous use, auto-off after 10 minutes of non use life. 0 to 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Measures 7.6" length by 4.1" width by 2.7" height. Tetraphenylborate method.

Manganese is one of the most common metals present in nature and is used in many industrial applications, for example, the production of fertilizers and in the pharmaceutical industry. Manganese salts are also used in iron alloys (steel manufacturing) and non-iron alloys as it improves their corrosion resistance and hardness. This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit a cuvette with a larger neck making it easier to add both sample and reagents. The cuvette is made from special optical glass to obtain best results. HI96748 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0 to 300micro g/L range, 1micro g/L resolution. +/-10micro g/L +/-3 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector. Approximately 40 hours of continuous use, auto-off after 10 minutes of non use life. 0 to 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Measures 7.6" length by 4.1" width by 2.7" height. Adaptation of the 1-(2-pyridylazo)-2-naphtol PAN method.

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 HI96717 measures phosphate content in water, wastewater and seawater in the 0.00 - 30.0 milligrams per liter range. 0.00 - 30.0 milligrams per liter range. 0.1 milligrams per liter resolution. +/-1.0 milligrams per liter +/-4 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector. Amino acid method, adapted from standard method for the examination of water and wastewater. 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.
