Overview of Nitrates and Measurement Importance
Bodpfexxyimsx Al Rswl

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.

Key Features:

HI 93728 Meter:

0.0 to 30.0 mg/L (NO₃-N)

Resolution:

0.1 mg/L

Accuracy:

±0.5 mg/L ±10% of reading

Light Source:

LED at 555 nm

Light Detection:

Silicon Photocell

Battery Type/Life:

1 x 9V with approximately 40 hours of continuous use.
