For Water Supply Inline Dissolved Oxygen Meter by BOQU
Product Overview
- For Water Supply Inline Dissolved Oxygen Meter by BOQU (DOG-20xx Pro series) is an online dissolved oxygen (DO) analyzer for continuous real-time DO and temperature monitoring. It is available for panel, wall or pipe mounting and comes from Shanghai Boqu Instrument Co., Ltd.
Product Features
- Wide DO measurement range: from ppb up to mg/L (0.00–20.00 μg/L and 0.00–20.00 mg/L) and 0.00%–200.00%.
- Fast response down to ppb levels and high accuracy (DO ±1%, temperature ±0.2°C).
- Two isolated 4–20 mA outputs, RS485 Modbus RTU communication, and two control relays (5 A).
- Temperature compensation options (PT1000 / NTC10K / 22K).
- Rugged hygienic construction, ABS flame-retardant housing (V0), IP65 protection, compact dimensions (144×144×104 mm, cutout 138×138 mm).
- Multi-language UI (English / Simplified Chinese) and low power consumption (4 W, 90–260 V AC).
Product Value
- Provides continuous, reliable DO data for process control and compliance, enabling faster decision-making and improved product/effluent quality.
- Sensitive ppb-level detection supports critical purity and environmental applications (e.g., ultrapure water, semiconductor processes, fermentation).
- Reduces operational cost per measurement point through durable probes, quick response (no warm-up), and simple, low-maintenance operation.
- Integration-ready outputs and relays allow straightforward automation and alarm/control implementation.
Product Advantages
- High sensitivity (ppb measurement) and fast, stable response for precise control.
- Long probe life with no required sensor warm-up time, lowering downtime and maintenance.
- Multiple output/communication options (dual 4–20 mA, RS485) and control relays for flexible system integration.
- Robust, hygienic, and weather-protected design (IP65) suitable for industrial and sanitary environments.
- Factory-direct supply and company support infrastructure for sales, service and timely response.
Application Scenarios
- Drinking water and municipal water treatment monitoring.
- Industrial wastewater and environmental monitoring.
- Pharmaceutical, food & beverage, and fermentation process control.
- Ultrapure water and microelectronics/semiconductor rinse-water monitoring.
- Chemical and power plant process streams and boiler/feedwater control.
