The eXact® Strip Micro Calcium Hardness 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.
The eXact® Strip Micro Calcium Hardness test strip comes in a bottle with 50 test strips used with the 525nm eXact®Photometers.
