About This
- DOUBLE CHECK - Each tester strip is designed with two identical color pads. If the color of the pads differs after testing, it indicates that the test may not be reliable and a new test should be performed.
- 50 WATER TEST STRIPS - Maximize the time between each purchase with the lowest cost-per-test water hardness test strips that are available.
- LONGEST SHELF LIFE - Desiccant design forms a dry force shield around the strips which also prevents the strips from going bad due to too much contact with moisture.
- EASILY THE MOST ACCURATE - DoubleCheck to weed out bad color pads, sample cup with pre-measured water level for the most optimum water to test strip ratio.
