Silicon, Si, is the most\nabundant element in the Earth’s crust, 28% of it by weight. Silicon is never\nfound free form in nature. In crystallized form it is only reactive under\nconditions of extremely high temperatures. Water and water vapor probably have\nlittle influence upon silicon solubility, because a protective surface layer\nof silicon dioxide is rapidly formed. Silicon binds with other elements to\nform various species of silica and silicate. The concentration of the soluble\nsilica molecules are important to aquaculture because they influence (and\nlimit) the growth of diatoms. In most waters, the predominant form of\ndissolved silica is monosilicic acid, which incorporates 2 water molecules.\nThe HANNA HI 770 Checker HC is accurate and affordable. This portable handheld\ncolorimeter features a resolution of 1 ppm (200 points) and +\/-2 ppm +\/-5% of\nreading accuracy. The contoured style of the HI 770 Checker HC fit in your\npalm and pocket perfectly and the large LCD is easy to read. The auto shut off\nfeature assures the battery life will not be drained if you forget to turn it\noff. The HI 770 Checker HC is simple to use. First, zero the instrument with\nyour water sample. Next, add the reagents in order, respecting all the\nindications. Last, place the vial into the Checker HC, press the operational\nbutton for about 3 seconds and the display will show the countdown prior to\nthe measurement or, alternatively, wait for 2 minutes after last reagent\nadding and press operational button.

Light\nDetector: silicon photocell. Environment: 0 to 50 degree C (32 to 122 degree\nF); RH max 95% non-condensing. Battery Type: 1.5V AAA. Auto-off: after two\nminutes of non-use.

In most waters, the predominant form of dissolved silica is monosilicic acid, which incorporates 2 water molecules. The HANNA HI 770 Checker HC is accurate and affordable. This portable handheld colorimeter features a resolution of 1 ppm (200 points) and +/-2 ppm +/-5% of reading accuracy.
