Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
- DOG-209F is an industrial polarographic dissolved oxygen (DO) probe from BOQU, designed for continuous on-line measurement in demanding environments. It comes with robust housing options (uPVC or 316L stainless steel) and a standard 5 m cable (customizable).
Product Features
- Measurement range: 0–20 mg/L; detection limit: 0.01 mg/L (20 °C).
- Principle: polarographic DO electrode with 50 µm permeable membrane.
- Temperature compensation options: PT100, PT1000, 22K, 2.252K, etc.; water temperature range 0–60 °C.
- Performance: drift
- Operational: polarization time ~60 min, minimum flow 2.5 cm/s, output current 50–80 nA per 0.1 mg/L (max 3.5 µA), polarization voltage 0.7 V.
Product Value
- Provides accurate, stable, and low-drift DO data for process control and compliance monitoring.
- Low maintenance and long calibration intervals reduce operating costs and downtime.
- Wide temperature compensation choices and rugged housing improve reliability across varied installations.
- Customizable cable length and mature sales/support network make integration and service convenient.
Product Advantages
- Built for harsh industrial conditions: robust materials (including 316L stainless steel) and stable polarographic design.
- High sensitivity (0.01 mg/L) and good accuracy (±0.1 mg/L) enable detection of low-oxygen conditions.
- Long sensor life (~2 years) and low drift (
- Flexible options and BOQU’s experienced technical team and distribution network ensure easier deployment and after-sales support.
Application Scenarios
- Urban sewage and municipal wastewater treatment plants.
- Industrial wastewater monitoring and process control.
- Aquaculture and fish farming oxygen management.
- Environmental monitoring of natural waters and effluent discharge.
- Any continuous DO measurement application requiring reliable, low-maintenance sensors.
