Safe to Use Optical Do Meter for Aquariums

Product Overview

- The BOQU DOG-3082 is a microprocessor-based, online dissolved oxygen (DO) meter marketed as an optical DO meter for safe use in aquariums and other water systems.

- It provides continuous, high-precision DO monitoring with automatic switching between ultra-low (ppb) and conventional (ppm) ranges (0–100.0 µg/L and 0–20.00 mg/L).

- Built for panel/wall/pipe installation, it has an aluminum IP54 housing and multiple interfacing and alarm options for integration into control systems.

Product Features

- Extremely high sensitivity and resolution: 0.1 µg/L (ppb) and 0.01 mg/L (ppm).

- Fast response: 98% of final value in

- Multi-display readouts (DO, temperature, output, time, state) and an all-English menu for easy operation.

- Temperature compensation options (Pt1000 / NTC22K / 2.252).

- Multiple outputs and communications: 4–20 mA analog, RS485 (Modbus RTU), plus two configurable relay alarms (high/low).

- Robust site performance: anti-electromagnetic interference design.

Product Value

- Ensures safer aquarium environments by providing continuous, accurate DO data to protect fish and aquatic life.

- Supports automated control and early-warning (relay alarms) to prevent hypoxia events and reduce animal loss.

- High precision (ppb capability) is valuable for sensitive or high-purity systems (research tanks, public exhibits, quarantine setups).

- Standard industrial outputs and Modbus allow easy integration with existing monitoring or PLC systems for centralized management.

Product Advantages

- Wide automatic measurement range (ppb → ppm) in one instrument, eliminating the need for separate meters.

- Excellent accuracy and high resolution for both ultra-trace and routine aquarium DO monitoring.

- Multiple interfaces (analog, digital, relays) and fast response time enable reliable, real-time control.

- Durable, interference-resistant design (IP54 aluminum housing) suitable for installation in typical aquarium and facility environments.

- User-friendly English menu and flexible installation options (panel/wall/pipe).

Application Scenarios

- Public aquariums and display tanks where continuous, reliable DO control is critical for animal welfare.

- Research and laboratory aquaria requiring high-sensitivity DO measurements.

- Aquaculture and hatcheries (recirculating systems, broodstock tanks) for optimized oxygen management.

- Water treatment, environmental monitoring, and industrial processes that need online DO measurement and alarm integration.

- Any controlled aquatic system that benefits from automated monitoring and integration with building or process control systems.
