Juliet Browning

My name is Juliet and my role at TES is to manage our Meteorological, AQMS and Teledyne API products. I have a bachelor degree in Biomedical Science and have spent the last 7 years as an Environmental Division Manager in an organisation that was predominantly concerned with water monitoring. I'm now looking forward to developing my knowledge across the Air Quality industry, in order to provide our customers and team with the most up to date and relevant information available. You can contact me at the Sydney office or on my mobile: 0421 875 646
