The eXact® Strip Micro Total 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.
ONLY FOR USE WITH OLDER eXact® METERS. SEE MANUAL FOR ALLOWABLE PART NUMBERS.
