MultiTest™ Copper

  • Measures all types of copper to less than 0.01 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

Copper kits are usually of two types: compleximetric or titration based. Some kits measure only ionic copper and others measure both ionic and chelated copper. This kit uses a highly sensitive catalytic compleximetric based procedure to measure all types of copper to less than 0.01 mg/L in marine or freshwater. MultiTest™ Copper performs over 75 tests and contains a reference sample for validation.


75 Tests

MultiTest™: Copper performs over 75 tests

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



Measures between 0–0.80 mg/L copper


Detectable changes on the color chart in 0.025mg/L & 0.0025 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.

  • Instructions

A: Actually, that amount of powder should last for all 75 tests. It only takes a few granules of the powder for the kit to work properly.

A: Yes, the included reference solution has a known value of 0.5mg/L. We recommend running your tank sample at the same time as the reference sample in the white well plate. This will help you to gauge the level of copper you have in your system based on the reference solution results. Keep in mind, that you use the reference solution in place of your tank sample when you run the reference test. You will also use 3 drops of Copper Reagent 2 in Step 2 when testing the reference solution.

A: You should not have to wait that long before you get a result. It should be at peak color no longer than 5 minutes.
