Nitrates are present in nature as a result of decomposition of organic microorganisms or due to their use as fertilizers. Nitrates reduce to nitrites, which in turn easily combine to form substances dangerous to man.
A maximum level of 45 mg/L (ppm) is established as a worldwide guideline for nitrate concentration in water. In Europe, the maximum consented level of nitrates in potable water is 50.0 mg/L (ppm), while in the USA the EPA has established a guideline for the maximum level of nitrate—nitrogen of 10 mg/L (NO-3-N), which corresponds to 45.0 mg/L of nitrates.
The HI 96728 meter measures the nitrate content in water and wastewater.
This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell.
Order Information: HI 96728 is supplied with sample cuvettes with caps (2), 9V battery and instruction manual. HI 96728C include photometer, sample cuvettes with caps (2 ea.), CAL CHECK standard cuvettes, 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case.

6,000 + (and growing) factories in our existing network are eager to make it for you.
When it comes to selling in stock products, we are no difference from many other Internet retailers, but we take pride in going extra miles to do something special for you: Have some products custom made for you.
We cannot do everything, but we usually can accommodate a certain changes in product options such as color, size, material, or minor design twist. We primarily work with vendors or factories, not individual artist or craftsman. For custom made products, we usually only cater to bulk size order that meets the minimum quantity requirement of a single factory run. Don't be shy. Ask. What we can accomplish may surprise you!
