Your cart is empty.For use with eXact Photometers, the eXact Strip Micro Total Hardness Low Range 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 bulk bottle of 50 tests.

I've been quite happy with these. They came included with the kit when I purchased the eXact 20 photometer. The results have been comparable to what we got from the lab for significantly less. We can run 100 tests for less than the price of one lab test.As the description says, you DO need an eXact photometer from the company to use the strips. Their site is sensafe dot com

There is not a comparison strip enclosed to compare the results with. The instructions are not complete enough to know what to do.
