If you want to ensure the ozone production is 6G/h or not, you can use ozone detector to detect the ozone output position. we have ozone detector can detect the ozone concentration. and you can calculate the ozone output accoding to the ozone concentration. here provide a formula for you reference: oxygen flow rater × ozone concentration ×60 /1000=ozone output ( G/H).And please make sure the oxygen source is clean & dry. If the humidity is high, we recommend add an air dyrer for oxygen unit.so that can ensure the oxygen source is good and ensure the ozone output.
