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 ?g/L range). It provides high-sensitivity DO monitoring (detection limit ~0.1 ?g/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).
