Dissolved Oxygen Sensor in Water - Bulk Production - BOQU
Product Overview
- BOQU DOG-208F is a ppb-class polarographic dissolved oxygen (DO) sensor designed for trace oxygen measurement in water (0–100 µg/L range). It provides high-sensitivity DO monitoring (detection limit ~0.1 µg/L at 20°C) for demanding industrial and high-purity water applications.
Product Features
- Polarographic sensor with platinum cathode and Ag/AgCl anode; electrolyte: 0.1 M KCl.
- Silicone rubber permeable membrane (imported) combined with steel gauze for impact and temperature resistance and good shape retention.
- SS316L electrode shell, double-shielded 5 m cable, and temperature compensation options (PT100, PT1000, 22K, etc.).
- Technical highlights: polarization voltage 0.7 V, polarization time >8 h, minimum flow ~5 cm/s, measurement error 60 days, operational temperature 0–60°C, sensor life ~3 years.
Product Value
- Delivers ultra-low-level, reliable DO readings that support process control, corrosion prevention, and product quality in sensitive systems.
- Reduces maintenance and downtime via long calibration intervals and robust construction, lowering operating cost and improving measurement confidence.
- Suitable for compliance and optimization in industrial water circuits where trace oxygen impacts performance and safety.
Product Advantages
- Very high sensitivity and low detection limit (ppb level) with tight measurement accuracy (±1 ppb).
- Durable, corrosion-resistant materials (SS316L, quality membrane, steel gauze) for long service life (~3 years).
- Stable output and low drift with comprehensive temperature compensation and double-shielded cable for reliable field use.
- Backed by BOQU’s quality assurance, testing, and application experience with exports and industry deployment.
Application Scenarios
- Trace DO monitoring in thermal power plants (including desalinated water systems) and boiler feed water.
- High-purity water systems and other industrial processes where ultra-low dissolved oxygen is critical (power industry, water treatment, and similar applications).
