Hanna Nitrate Photometer
Hanna Nitrate Photometer
* Simple-to-use aquarium tester with quick, accurate results * Measures nitrate levels in water through light refraction * Positive-locking system ensures correct cuvet placement for error-free results Simple-to-use, professional-grade tester measures nitrate levels in your aquarium. Contains a lab-quality light emitting diode encased in a high-impact plastic housing. Includes two 10 ml cuvets and a 9-volt battery. Exclusive positive-locking system prevents user-error, while automatic shutoff feature conserves battery life. Uses light refraction to measure water turbidity from nitrate - which is formed during the decomposition of organic wastes. Measures between 0 to 30.0 mg/L. For Freshwater use only. Nitrate Reagent are precisely measured, single-use packets for use with 10 ml cuvets. Contains 100 packets. 2 year manufacturer's warranty.

Nitrate Photometers
Nitrates are present in nature as a result of the decomposition of organic microrganisms or due to their use as fertilizers.
HI 93728 and HI 93828 are hand held meters suited for field measurement. Nitrates reduce to nitrites, which in turn easily combine to form substances dangerous to man. A maximum level of 45 mg/L 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, 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 Hanna solutions are HI 93728 and HI 93828, hand held meters suited for field measurement. Reading procedures have been made as simple as possible to allow everyone to perform accurate nitrate measurement. The kits provide you with all you need for field measurement: photometer, reagents and apparatus perfectly fitted in a rugged carrying case. HI 93728 reads nitrogen nitrate from 0 to 30 mg/L (NO-3-N); multiply the readout by a factor of 4.43 and you can read up to 133 mg/L of nitrate (NO). HI 93828 reads nitrate directly in mg/L of NO-3, from 0 to 100 mg/L. With a normal 9V battery you will be able to get more than 300 measurements. The auto shut-off feature (after 10 minutes of non-use) guarantees a long battery life.
HI 93728 is supplied complete with 2 cuvets, battery and instructions. HI 93728C, kit includes HI 93728, hard carrying case and reagents. HI 93828 is supplied complete with 2 cuvets, battery and instructions. HI 93828C, kit includes HI 93828, hard carrying case and reagents.
