The Waltron 9165 Luminescent Dissolved Oxygen Analyzer utilizes intuitive touchscreen control to provide reliable luminescent technology for measuring dissolved oxygen in water at ppb levels. This technology offers superior benefits and cost savings compared to traditional DO sensing technologies.

The 9165 provides high accuracy and long-term stability on an easy-to-use platform. Full touchscreen control includes sample point labeling for easy identification. Plug-and-play addition of multiple sensors allows flexible system configuration, and up to four sample streams can be monitored on one electronics platform.

Four configurable 4-20mA analog outputs provide flexible signal transmission, while NC or NO alarms can be configured for general, temperature, or concentration alerts. Dynamic sampling rates from 10-999 seconds adapt to measurement requirements. With resolution of 0.1 ppb, units selectable in ppb or ppm, and an IP65 (NEMA 4x) enclosure, the 9165 is suitable for various online analysis applications across many industries.
