9165 Dissolved Oxygen Analyzer
Range: 0-45ppm
Range: 0-2000ppb
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 a variety of online analysis applications throughout many different industries.
