BOQU Dissolved Oxygen Meter Dissolved Oxygen Meter Supply

Product Overview

1) Product overview

Product Features

- Model: BOQU DOG-2082YS Digital Optical Dissolved Oxygen Meter for online dissolved oxygen (DO) and temperature measurement.

Product Value

- Uses a digital optical DO sensor with direct RS485 Modbus connection.

Product Advantages

- Panel / wall / pipe mounting; IP65 ABS housing; mains powered (90–260 VAC).

Application Scenarios

2) Product features

- Optical digital sensor with special light-source technology for long sensor life and fast, precise measurements.

- Measurement ranges: 0–20.00 mg/L DO, 0–200.00% saturation, temperature −10.0–100.0 °C; accuracy ±1% FS (DO) and ±0.5 °C (T).

- Outputs: two isolated 4–20 mA channels (DO and temperature) and RS485 Modbus RTU communication.

- Built-in datalogger with history curve display and three relays (high/low alarms and cleaning time relay).

- Designed for harsh environments and low maintenance.

3) Product value

- Provides continuous, reliable online DO and temperature data for process control and regulatory compliance.

- Low-maintenance optical sensing reduces downtime and operating costs versus consumable electrochemical probes.

- Isolated analog outputs and Modbus enable easy integration into DCS/SCADA systems for remote monitoring and automated control.

- Data-logging and alarm relays improve traceability and rapid response to process excursions.

4) Product advantages

- Optical sensing: maintenance-free operation and longer lifetime compared with conventional electrodes.

- High precision and fast response suitable for tight process control.

- Flexible interfacing: isolated 4–20 mA outputs + RS485 Modbus for broad system compatibility.

- Robust design: IP65 protection, multiple mounting options, and built-in relay logic for local alarm and cleaning control.

- Cost-effective with quality-controlled manufacture and competitive pricing.

5) Application scenarios

- Industrial wastewater treatment and effluent monitoring (aeration basins, outlet compliance).

- Drinking water treatment and distribution monitoring.

- Environmental water quality monitoring.

- Process control in pulp & paper, chemical industry and other water-using industrial processes.

- Any online DO monitoring application requiring reliable, low-maintenance, integrable measurement.
