Application Scenarios
2) Product features
- Measuring range: 0–100.0 µg/L (ppb) and 0–20.00 mg/L (ppm) with automatic switching.
- Resolution/accuracy: 0.1 µg/L (ppb) & 0.01 mg/L (ppm); accuracy: ppb ±1.0% FS, ppm ±0.5% FS.
- Temperature compensation: Pt1000 / NTC22K / 2.252; automatic temp range 0–60 °C; response
- Outputs & interfaces: 4–20 mA, RS485 (Modbus RTU), and two alarm relays.
- Construction/installation: IP54 aluminum housing; panel, wall or pipe mounting.
- Additional features: multi‑display (DO, temperature, outputs, status, time), English menus, anti‑electromagnetic interference design.
3) Product value
- Enables continuous, high‑precision dissolved oxygen monitoring from ppb to ppm, supporting process control and quality assurance in sensitive applications (e.g., pure water, steam sampling).
- Multiple output options and Modbus communication facilitate integration into PLC/SCADA systems for automated control and remote monitoring.
- Rugged housing and anti‑interference design increase reliability in industrial environments, reducing downtime and maintenance needs.
4) Product advantages
- ppb‑class sensitivity allows accurate measurement in ultra‑low DO applications.
- Automatic wide‑range switching removes the need for manual range changes and reduces risk of measurement gaps.
- High resolution and fast response time provide timely, reliable data for process decisions.
- Flexible mounting and standard communication interfaces simplify installation and system integration.
- Backed by manufacturer production controls and experience (Shanghai Boqu Instrument Co., Ltd.), with stated quality management and export track record.
5) Application scenarios
- Steam sampling and condensate monitoring in power plants and boiler systems.
- Pure water systems for pharmaceuticals, semiconductors and laboratories where ultra‑low DO is critical.
- Industrial process control and chemical plants requiring continuous DO monitoring.
- Wastewater treatment and environmental monitoring where both low and higher DO ranges must be covered.
- Aquaculture and water utilities where integration with control systems and alarm functions are needed.
