3) Product value
- Delivers precise, stable dissolved oxygen and temperature data for regulatory compliance, process control and quality assurance.
- Multiple isolated outputs and Modbus enable easy integration with PLCs, SCADA and building automation for remote monitoring and control.
- Large local data logging and robust construction reduce maintenance visits and data-loss risk, supporting continuous operations and analytical traceability.
- Flexible installation options and cleaning/alarm functions improve uptime in demanding industrial and environmental applications.
4) Product advantages
- Wide measurement range including ppb-level detection for high-sensitivity applications.
- High accuracy, stable electrode current measurement and temperature compensation for reliable readings.
- Industrial connectivity (isolated 4–20 mA, RS485 Modbus) and configurable relays for seamless system integration and automated responses.
- Rugged IP65 enclosure and versatile mounting (panel/wall/pipe) for harsh sites; extensive logging capacity for long-term trending.
- Backed by BOQU’s quality control, industry experience and customer support for cost-effective deployment.
5) Application scenarios
- Wastewater treatment monitoring and control (aeration optimization, compliance reporting).
- Drinking water quality monitoring and environmental/water-resources monitoring stations.
- Fermentation and food & beverage production process control where DO affects product quality.
- Industrial process water and cooling systems where DO must be controlled to prevent corrosion or biofouling.
- Aquaculture, laboratories and other sites requiring continuous high-sensitivity dissolved oxygen measurement and data logging.
