Residual Chlorine Total Nitrogen Tester

The residual chlorine and total nitrogen tester detects the levels of residual chlorine and total nitrogen in water through chemical reactions. Residual chlorine is measured using the DPD colorimetric method, while total nitrogen is determined by converting nitrogen-containing compounds into nitrates through high-temperature digestion before detection. It is used to monitor the effectiveness of drinking water disinfection and the degree of water eutrophication, and is commonly employed in daily testing at water treatment plants and wastewater treatment facilities.
Selection
Select the measurement range based on the type of water being tested. Drinking water is suitable for a range of 0-5 mg/L, while wastewater requires a wider range. Consider operational convenience: portable devices are suitable for on-site testing, while benchtop models are better for laboratory use. Ensure the stability of the supply of supporting reagents and verify that the instrument complies with national testing standard method requirements.
