Water colorimeter HI7134

portable

HI7134 Phosphate Low Range Checker® Handheld Colorimeter (HC) bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source at a specific wavelength and a light-sensing detector to precisely determine absorbance and ion concentration. The Pool Line Low Range Phosphate Checker HC uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit. Precise measurements with no guessing of color Laboratory measurements at a fraction of the cost Simple, intuitive operation HI7134 Pool Line Checker HC is designed for the measurement of low levels of phosphate in swimming pools, hot tubs, and spas. The HI7134 can measure phosphate from 0.00 to 2.50 ppm (as PO43-). Phosphate can be introduced into a swimming pool by either the water that is being added or the breakdown of organic materials such as leaves and grass clippings. Phosphate is commonly added to municipal drinking water to minimize the corrosion of pipes in the distribution system. At high levels phosphate is a nutrient that encourages algae growth. From pool companies, it is recommend to keep phosphate less than 1000 ppb (1.0 ppm) to prevent algae from growing. The water can be treated with chemicals to remove phosphate and the HI7134 Pool Line Checker can be used to monitor and track changes to the phosphate level. The contoured style of this Checker HC fits in the palm of your and the large LCD is easy to read.
