Checker Disk Test Kits

Hanna Checker disk test kits use the technology of colourimetric kits to provide greater accuracy and resolution. The Checker disk is a colour comparison wheel shaded from dark to light in proportion to the concentration of the chemical parameter being tested.

All the user needs to do is put both the blank and reacted cuvets  inside the Checker disk. By turning the wheel, the user can then visually find the concentration that best equals the reacted sample.

This technique enhances resolution and accuracy.
