Thank you for this lecture video. I am about to do a promotional exam for my workplace at a water treatment facility from lab technician to chemist and I know for sure my oral exam will ask regarding about ammonia meters and how to troubleshoot and obtain quality control data. Your video is very helpful for my studies for that promotional interview oral exam. Thanks again for sharing
