Expert in Water Quality Measurement and Water Treatment Project Since 2007
Dissolved Oxygen Meter Inline Dissolved Oxygen Meter for Potable Water Made in China
Product Overview
- Model: DOG-2092Pro Inline Dissolved Oxygen Meter (Made in China) by BOQU.
- Purpose: Continuous online measurement of dissolved oxygen (DO) and temperature for potable water and industrial water processes.
- Key physical/specs: IP65 ABS housing, panel/wall/pipe mounting, dimension 98.2 × 98.2 × 128.3 mm, cutout 92 × 92 mm. Languages: English and Simplified Chinese.
Product Features
- Measurement: DO range 0.00–20.00 mg/L and 0.00–200.00% saturation; temperature -10.0℃ to 130.0℃.
- Accuracy and stability: DO accuracy ~1%, temperature ±0.2℃; fast response, long probe life, no sensor warm-up time required.
- Outputs & control: two independent 4–20 mA outputs, RS485 Modbus RTU communication, two high/low relays (5 A).
- Temperature compensation options: PT1000 / NTC10K / NTC22K. Low power consumption (4 W), wide AC input (90–260 V).
Product Value
- Ensures water quality and safety by accurately tracking DO levels important to drinking water, wastewater discharge compliance, and biological treatment control.
- Helps prevent equipment damage and product spoilage caused by unwanted oxidation in industrial processes (e.g., steam generation).
- Enables process control optimization, regulatory compliance, and consistent product/environmental quality through continuous monitoring and remote data integration.
Product Advantages
- Reliable, stable continuous measurement with fast response and long sensor life.
- Flexible installation (panel, wall, pipe) and industrial-grade protection (IP65) for varied site conditions.
- Integrated outputs and digital communication (4–20 mA + RS485 Modbus) simplify connection to PLC/SCADA systems.
- Backed by BOQU’s R&D, manufacturing and service capability—experienced technical team, pre-/after-sales support, and timely customer response.
Application Scenarios
- Municipal and industrial wastewater treatment (aeration control, discharge compliance).
- Drinking water production and biofiltration stages.
- Ultrapure water systems and process water monitoring.
- Fermentation, food and beverage production, and other bioprocesses requiring DO control.
- Industrial processes sensitive to oxygen (e.g., boiler/steam systems, power plants) where oxygen must be minimized or tightly controlled.
