For use with eXact Photometers, the eXact Strip Micro Manganese incorporates the patented eXact reagent delivery system created by Industrial Test Systems, Inc. which is ideal for technical and non-technical users. By dipping the eXact strip into a photometer cell, the exact amount of reagent is released into the water causing a change in color or turbidity. The change is measured by an eXact photometer giving the user fast and accurate results. Each unit consists of a kit containing 24 Mn Strip 1, 24 Mn Strip 2, and dropper bottle with liquid reagent for 24 tests.
