Pool
Line Phosphate low range Checker HC® colorimeter: Range 0.00 to 2.50 ppm
(mg/L)
HI-7134
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
HI-7134
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. The auto shut-off feature assures the battery life
will not be drained if you forget to turn it off.
To
perform a measurement the instrument a water sample is placed into a
cuvette and the meter is zeroed. Next, a reagent is added that will react
with phosphate to produce a blue color. Last, place the vial into the
Checker HC, press the button and read the results. It’s that easy.
