  • 由於使用了特殊的成分, Salifert 測試不受這些干擾,可以使水能快速且持續地發生顏色變化,就算是微量的亞硝酸鹽亦能檢測出來。
  • 一盒Salifert 檢測試劑盒足以進行 50 次測試。
  • Salifert 檢測試劑盒僅適用於在海水中。


  1. 將要進行測試的水(1 ml)用注射器抽出然後放入測試容器中
  2. 加入一勺 NO2 粉末。輕輕攪拌測試容器的內容物 20 秒。然後靜置 60 秒。
  3. 將測試容器放在顏色圖表的白色部分上,比較顏色。讀取檢測到的亞硝酸鹽百分比。兩種色調之間的顏色對應於亞硝酸鹽中間體的濃度。亞硝酸鹽值以 mg/L 為單位。如果您需要測試亞硝酸鹽的氮的濃度,則觀察到的結果必須乘以 0.3。

Salifert NO2

Nitrites are converted into nitrates by the natural cycle of life in the aquarium. The nitrates thus formed are converted into harmless nitrogen through denitrification. This happens in areas devoid of oxygen between the live rocks. Before being transformed into nitrate nitrogen is first converted into nitrites. When for some reason this cycle can not be completed nitrites can be present in significant amounts and detected by a test that does not suffer from interference with the amine.

The Salifert test for nitrates is not subject to these interferences due to the special components used. These same components give a color change to the water to be tested quickly and on, to detect even small amounts of nitrites. E'probabilmente test for nitrites faster and more accurate on the market.

  •  Sufficient for 60 tests
  • Can be used for marine water, freshwater and garden pond water


  1. Put a syringe with 1.0 ml of water to be tested in the container of the test.
  2. Add a level scoop of powder NO2. Gently stir the contents of the container of the test for 20 seconds. Let stand for 60 seconds.
  3. Place the container of the test on a white part of the color chart ee compare the colors. Read the percentage of nitrite detected. A color between two shades of color corresponds to a concentration of nitrite intermediate. Nitrite values are given in mg / L. If you prefer the concentration Nitrite - Nitrogen, the results observed must be multiplied by 0.3.
