Jennifer V Posted February 21, 2022 Share Posted February 21, 2022 It's a little hard to tell but it looks like ~10 ppm to me. 1 1 Link to comment Share on other sites More sharing options...
Guppysnail Posted February 21, 2022 Share Posted February 21, 2022 I’m going to say closer to 20-40 but I have an old tablet so it may be skewing it a bit. 1 Link to comment Share on other sites More sharing options...
Torrey Posted February 21, 2022 Share Posted February 21, 2022 If you have access to another phone, use the other phone's flashlight to put under the test vial. It will illuminate from underneath, and make it much easier to read. I think it looks like 10 ppm, my spouse thinks 20 ppm 1 Link to comment Share on other sites More sharing options...
