Nitrates are inorganic salts that occur as a natural or manmade contaminants in drinking water. High nitrate levels indicate the presence of other pollutants, such as bacteria or pesticides, as these follow the same path as the nitrate into the water supply. Our nitrate water test kit is based on a colour comparison method. It is a very sensitive one and giving distinct colours which are easily comparable with the chart provided.
