- Can be fitted with DOG-208F polarographic ppb electrode and automatically switches measurement range between ppb and ppm for wide?range monitoring.

Application Scenarios

2) Product features

- Measuring range: 0–100.0 ?g/L (ppb) and 0–20.00 mg/L (ppm) with automatic switching.

- Resolution/accuracy: 0.1 ?g/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.
