Hanna CheckerHC SeriesHandheld Colorimeters

The Hanna CheckerHC bridges the gap between simple chemical test kits

and professional instrumentation. Chemical test kits are not very accurate

and only give 5 to 10 points resolution while professional instrumentation can

cost hundreds of dollars and can be time consuming to calibrate and maintain.

The CheckerHC is both accurate and affordable.

The contoured style of the CheckerHC fits in your palm and pocket perfec tly,

while 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.

Color of WaterHandheld Colorimeter

Ideal for water quality

True color is caused by dissolved compounds in water and can be both natura

artificial. Apparent color is caused by both dissolved and suspended solids. Co

is measured in Platinum-Cobalt units (PCU). The AWWA recommends 15 PCU

The term true color is defined as the color of water from which turbidity

has been removed. The term apparent color includes not only color due

to substances in solution, but also color that is due to suspended matter.

Apparent color is determined on the original sample without filtration or

centrifugation. In some highly-colored industrial wastewaters, color is

contributed principally by colloidal or suspended material. In such cases, botrue color and apparent color should be determined.

To determine true color, turbidity must be removed before analysis. Metho

for removing turbidity without removing color vary. Filtration yields results

that are reproducible from day to day among laboratories, however, some

filtration procedures may also remove some true color. Centrifugation avoi

interaction of color with filter materials, but results vary with the sample

nature, size, and speed of the centrifuge. When samp le dilution is necessa

whether it precedes or follows turbidity removal, it can alter the measured

color. Acceptable pretreatment procedures are included with each method

The pretreatment method should be stated when reporting the results.

Fluoride Low Range and HighRangeHandheld Colorimeters

Ideal for water quality

Fluoride is one of the very few chemicals that have been shown to cause

effects on teeth at low concentrations in drinking water, but excessive

exposure to fluoride in drinking water, or in combination with exposure to

fluoride from other sources, can give rise to a number of adverse effects.

A 1994 World Health Organization expert committee suggested a level of

fluoride from 0.5 to 1.0 ppm, depending on climate. Bottled water typicallyhas unknown fluoride levels, and some domestic water filters remove som

or all fluoride.

Nitrite Low Range, High Range andMarine Nitrite Ultra Low RangeHandheld Colorimeters

Nitrification is the biological oxidation of ammonia (ammonium ion) into

nitrite, followed by the oxidation of nitrite to nitrate. The first step of this

two-step process is carried out in an aquarium by nitrifying bacteria. During

this quick process, the ammonium levels drop while the nitrite levels increase.

Since nitrite is just as harmful as ammonia, nitrite levels should be maintained

at immeasurable levels. A mature biological filter should be able to keepnitrite levels low.

PhosphorusHandheld Colorimeters

Ideal for aquaculture

Plants, algae and phytoplankton require phosphorus for nourishment and

utilize phosphorous as a component of cell tissue. When organic matter such

as plant tissue, dead fish, algae, or uneaten food breaks down aerobically

(with oxygen), phosphate is produced, This results in rapid oxygen depletion

of aquarium water, which in turn suffocates aquatic life and compounds

the problem.

Phosphorus concentration in water is monitored because it causes corrosion

when present in levels too high.

HI770 HI705

Silica High Range and Low RangeHandheld Colorimeter

Silica is the name given to silicon dioxide, SiO2. Silicon (Si), is the most abunda

element in the Earths crust, 28% of it by weight. Silicon is never found free

form in nature. In crystallized form it is only reactive under conditions of

extremely high temperatures. Water and water vapor have little influence u

silicon solubility, because a protective surface layer of silicon dioxide is rapid

formed. Silicon binds with other elements to form various species of silica an

silicate. The concentration of the soluble silica molecules are impor tant to

aquaculture because they influence (and limit) the growth of diatoms. In mowaters, the predominant form of dissolved silica is monosilicic acid, which

incorporates two water molecules.
