Overview of Nitrates and Measurement Importance
Nwjdpovmvbxsfx Aafon
Nitrates are naturally occurring compounds produced from the decomposition of organic matter or from fertilizers. However, they can be converted to nitrites, which pose health risks.


Guidelines for Nitrate Levels:
Global Maximum: 45 mg/L for nitrates in water.
Europe: 50 mg/L for potable water.
USA (EPA): 10 mg/L for nitrate nitrogen (NO₃-N), which equates to 45 mg/L of nitrates.
HANNA® HI 93728 and HI 93828 Meters
These handheld meters are designed for field measurements of nitrate levels with ease and accuracy.
