Hanna HI-96728 Nitrate Meter
The HI-96728 portable photometer is for the measurement of Nitrate. Nitrate is formed in water mainly through rainfall, decomposition of organic matter, and runoff from manmade pollutants such as sewage waste and fertilisers. Almost all surface waters have a measurable level of nitrate, and a moderate amount is considered beneficial. Large amounts of nitrate, however, can lead to eutrophication which may result in decreased levels of dissolved oxygen in the water.
Note: To ensure accurate results, perform the tests at room temperature, between 18 °C and 28°C.
For best result: Intensely coloured samples or suspended matter in large amounts will cause interference. Therefore sample should be adequately treated before performing the test.
