9165 Dissolved Oxygen Analyzer
Ranges: 0-20ppm, 0-45ppm, 0-2000ppb, 0-200ppb
The Waltron 9165 Luminescent Dissolved Oxygen Analyzer (LDO) utilizes optical (luminescent) technology for measuring dissolved oxygen in water at extremely low to sub-ppb levels, independent of flow. Luminescent technology features superior benefits and cost savings compared to traditional dissolved oxygen sensing technologies, including ease of maintenance and operation. The 9165 provides high accuracy with excellent long-term stability and can be used in various online analysis applications throughout many industries.
