  • Easy and accurate By Matt on 5/23/2017

    I used this to test how well my home carbon filter was working. Regular test strips were showing no chlorine post filtration but I was still getting a chlorine flavor and smell. With this it helped me properly get a proper flow rate to put my chlorine level down to 0 ppm.
