This dissolved Ozone Monitor can read ozone levels up to .75PPM. This unit is very easy to use and has a digital display which makes it easy to read.
You have high standards, and the new ozone test from CHEMetrics will surpass them. This new kit features an innovative self-zeroing technology in conjunction with the broadly accepted indigo method. Only one ampoule is required per test. That gives you greater speed, efficiency and savings. The kit concentration range matches FDA testing requirements for bottled water: 0-0.75 ppm.
