DO9100 Dissolved Oxygen Analyzer High-Precision Polarographic Sensor for Real-Time Monitoring

Q: What are the key features of the Hach DO9100 dissolved oxygen analyzer?

A: The Hach DO9100 polarographic oxygen analyzer offers continuous dissolved oxygen measurement, automatic temperature compensation, and a user-replaceable sensor membrane. Its robust design ensures reliable performance in water treatment and industrial applications.

Q: How does a polarographic oxygen analyzer differ from other dissolved oxygen sensors?

A: Polarographic oxygen analyzers like the DO9100 use a silver-gold electrode system and oxygen-permeable membrane to measure partial pressure, while optical sensors rely on fluorescence quenching. This electrochemical method provides stable, maintenance-friendly operation.

Q: What maintenance does the dissolved oxygen analyzer DO9100 require?

A: Regular maintenance includes monthly membrane/sensor cap replacement, electrolyte refill every 2-4 weeks, and calibration checks. The analyzer's modular design simplifies these tasks to ensure measurement accuracy.

Q: Can the DO9100 dissolved oxygen analyzer handle wastewater applications?

A: Yes, the DO9100 is specifically engineered for harsh environments like wastewater treatment. Its durable sensor resists fouling and includes automatic cleaning functions for sustained reliability in contaminated water.

Q: How often should I calibrate the polarographic oxygen analyzer DO9100?

A: Calibrate the DO9100 dissolved oxygen analyzer weekly under normal conditions, or more frequently in critical processes. The one-button calibration process uses either air-saturated water or zero oxygen solution for quick adjustments.
