Dissolved Oxygen Sensor Price - for Workplace - BOQU
Product Overview
- Model: DOG-209FYA optical dissolved oxygen sensor from BOQU (Shanghai Boqu Instrument Co., Ltd.).
- Solid construction options: CPVC (or PVC) or Stainless Steel 316 body with replaceable membrane cap module and M9 male connector; rated IP68.
- Measurement range and outputs: DO 0–20 mg/L, saturation 0–200%, working temperature ?5 to 50 °C, output 4–20 mA.
Product Features
- Optical (luminescence-based) sensing technology for dissolved oxygen.
- Grit-mesh metal membrane replacing the traditional diaphragm for higher stability and mechanical strength.
- Replaceable membrane cap and expected luminophore module life ≈ 2 years.
- Fast response: ~30 s to 90% (T90), ~60 s to full; built-in temperature sensing.
- High accuracy: DO ±0.1 mg/L, temperature ±0.2 °C, sat% ±1.0%.
Product Value
- Provides accurate, repeatable DO measurements for process control and environmental monitoring.
- Durable, maintenance-minimizing design reduces downtime and lifetime operating costs.
- IP68 rating and rugged construction enable reliable operation in harsh or wet environments.
- 4–20 mA output simplifies integration into existing control and monitoring systems.
Product Advantages
- Improved membrane design delivers better mechanical stress resistance and stability versus conventional sensors.
- Maintenance-free or low-maintenance operation thanks to optical sensing and robust membrane module.
- Quick response and high accuracy support tighter control of biological and chemical processes.
- Modular, replaceable parts (membrane/luminophore) simplify servicing and extend service life.
Application Scenarios
- Municipal and industrial wastewater treatment plants (continuous DO monitoring and control).
- Aquaculture systems (ponds, tanks) for oxygen management.
- Environmental monitoring stations and field sampling where rugged, IP68 devices are needed.
- Process control in industrial water treatment and other workplaces requiring reliable dissolved oxygen measurement.
