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 milligrams per liter (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 milligrams per liter (ppm), while in the USA the EPA has established a guideline for the maximum level of nitrate (nitrogen) of 10 milligrams per liter (NO-3-N), which corresponds to 45.0 milligrams per liter of nitrates. The HI96728 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. HI96728 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.0 - 30.0 milligrams per liter pH range. 0.1 milligrams per liter pH resolution. +/-0.5 milligrams per liter +/-10 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector. 0 - 50 degree C (32 - 122 degree F); RH maximum 95 percent non-condensing environment. Auto-off: after 10 minutes of non-use in measurement mode, after 1 hour of non-use in calibration mode with last reading reminder. Measures 7.6" length by 4.1" width by 2.7" height. Adaptation of the photometric method.

For use with eXact Photometers, the eXact Strip Micro Per acetic Acid incorporates the patented eXact reagent delivery system created by Industrial Test Systems, Inc. which is ideal for technical and non-technical users. By dipping the eXact strip into a photometer cell, the exact amount of reagent is released into the water causing a change in color or turbidity. The change is measured by an eXact photometer giving the user fast and accurate results. Each unit consists of a bulk bottle of 100 tests.

At normal temperatures chromium is corrosion-resistant. For this reason, it plays an important role in the plating industry as well as cooling towers. In addition, it has certain qualities that make it useful in the production processes of the textile industry. The HI 96749 meter measures the hexavalent chromium (Cr VI) content in water and waste waters samples.

The HI96730 measures the molybdenum content in water and wastewater. The 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. The cuvette has a very important role because it is an optical element and thus requires particular attention. It is important that both, the measurement and the calibration (zeroing) cuvettes, are optically identical to provide the same measurement conditions. Whenever possible use the same cuvette for both. It is necessary that the surface of the cuvette is clean and not scratched to avoid interference due to unwanted reflection and absorption of light. It is recommended not to touch the cuvette walls with hands. Furthermore, in order to maintain the same conditions during the zeroing and the measuring phases, it is necessary to close the cuvette to prevent any contamination. HI96730 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.0 to 40.0 milligrams per liter pH range. 0.1 milligrams per liter pH resolution. +/-0.3 milligrams per liter +/-5 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 420nm light detector. Approximately 40 hours of continuous use, auto-off after 10 minutes of non use life. 0 to 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Measures 7.6" length by 4.1" width by 2.7" height. Adaptation of the mercaptacetic acid method.
