These Low Range Chromium test strips incorporate the patented eXact reagent delivery system created by Industrial Test Systems, which is ideal for technical and non-technical users.
By dipping the strip into the vial, the exact amount of reagent is released into the water causing a change in color or turbidity. The change is measured by comparing the colored water in the vial to a color chart giving the user fast and accurate results.
