MultiTest™ Nitrite/Nitrate

  • Measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 mg/L
  • Multi-cavity plate for simultaneous testing of up to 6 tests at the same time
  • Includes reference for test validation
  • Marine or freshwater

    Nitrite is toxic and should be undetectable in any well established aquarium. During cycling, it may exceed 20 mg/L. Nitrate is relatively non-toxic, but it is advantageous to control it to under 20 mg/L.

    MultiTest™ Nitrite/Nitrate measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 mg/L in marine or freshwater. The values reported by this kit are expressed as nitrite and nitrate rather than nitrogen (to convert to nitrogen, simply divide by 3.3 and 4.4, respectively). It performs over 75 tests and contains a reference sample for validation.


    75 Tests

    MultiTest™ Nitrite & Nitrate performs over 75 tests

    And with the multi-cavity test plate, multiple tests can be run at the same time.



    Measures between 0-25 mg/L nitrite and 0–50 mg/L nitrate


    Detectable changes on the color chart in 0.1–1 mg/L increments

    Reference Sample

    It isn't necessary to run a reference test to use this kit; however, its proper performance can be validated by running a test in the normal manner except that the reference sample is used in place of aquarium sample. You might choose to run a reference test if you have cause to believe the test is giving incorrect results.

    Color Chart

    All MultiTest™ test kits come with an easy-to-read color chart. It features a 5 cm viewing window to help isolate color and match as closely as possible to the test sample

    Opaque Multi-Cavity Test Plate

    All MultiTest™ test kits are read from an opaque white test plate. The sliding color chart along with the six-cavity test plate allows for easy reading and comparisons of several samples at the same time.
