Pool Line Copper High Range Checker - HI7024


GST and Shipping charges are extra

HI7024 Pool Line High Range Copper Checker® HC (handheld colorimeter) 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 such as an LED or tungsten lamp with a filter and a light-sensing detector to precisely determine absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Pool Line Copper 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


  Add to wish list

In certain regions Copper can be found naturally in groundwater. Copper can also found in small amounts in the drinking water supplied by a municipality. Other sources of copper include any corrosion from piping and heat exchangers. Copper is normally not a concern but with pools the level can build up as water is evaporated and replaced. High levels of copper are undesirable in swimming pools, hot tubs, and spas, as it can stain bathing suits, hair, and other surfaces green. It can also cause the water to have an undesirable color when high levels of chlorine are present.

HI7024 Pool Line Checker Handheld Colorimeter is designed for the measurement of copper in swimming pools, hot tubs, and spas. The contoured style of the Checker fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.

To perform a measurement with the instrument a water sample is placed into a cuvette and the meter is zeroed. Next, a reagent is added that will react with the copper in the water sample. Last, place the vial into the Checker, press the button and read the results. It’s that easy.
