Optical Do Meter Dissolved Oxygen Meter Wholesale - BOQU

Product Overview

Product: Optical DO Meter — BOQU DOG-2082X

Product Features

1) Product overview

Product Value

- Industrial-grade optical dissolved oxygen (DO) meter model DOG-2082X from BOQU.

Product Advantages

- Measures DO in multiple units (%, ppm/mg·L?1, ppb/?g·L?1) and temperature with selectable temperature compensation (Pt1000 or NTC22K).

Application Scenarios

- Rugged instrument available for panel, wall or pipe mounting; inspected before delivery and sold wholesale.

- IP65 protection, wide supply voltage (90–260 VAC) and low power consumption (

2) Product features

- DO ranges: 0.0–200.0% ; 0.00–20.00 ppm ; 0.0–200.0 ppb (multi?unit readout).

- High resolution and accuracy (unit-dependent resolution ~0.1/0.01/0.1 and accuracy examples ±0.2 / ±0.02 depending on unit); temperature resolution 0.1 °C and ±0.2 °C accuracy.

- Electrode current measurement range ?2.0 to +400 nA with high current accuracy; polarization ?0.675 V.

- Environmental compensation: pressure 500–9999 mBar and salinity 0.00–50.00 ppt.

- Outputs and interfaces: isolated 4–20 mA outputs (DO and temperature), RS485 Modbus RTU (baud 9600/19200/38400), up to three relays (max 5 A), multifunction relay, and relay timing/cleaning controls.

- Large onboard datalogger (up to 500,000 records), backlit dot-matrix display, multilingual UI (English/Traditional/Simplified Chinese).

3) Product value

- Reliable, repeatable DO measurement for process control, compliance and quality assurance.

- Large data logging and Modbus connectivity enable remote monitoring, historical traceability and integration with SCADA/DCS systems.

- Built-in compensation (temp, pressure, salinity) and cleaning/control relays reduce manual intervention and improve measurement stability.

- Flexible mounting and robust IP65 design make it suitable for harsh industrial and field environments, lowering maintenance and downtime costs.

4) Product advantages (differentiators)

- Multi-unit display and wide measurement range cover applications from trace DO (ppb) to saturation percent, avoiding the need for multiple instruments.

- Isolated 4–20 mA outputs and RS485 Modbus RTU provide noise-resistant, industry-standard communications for easy system integration.

- High electrode current sensitivity and precision parameters support accurate readings even at low DO concentrations.

- Large internal memory (500k records) plus programmable cleaning and relay logic for automated control sequences.

- Robust build, flexible installation options (panel/wall/pipe), and IP65 protection for reliable operation in industrial/wet environments.

5) Application scenarios

- Wastewater treatment plant DO monitoring and aerobic process control.

- Drinking water quality monitoring and treatment plant control.

- Environmental monitoring (rivers, reservoirs, field stations).

- Fermentation, biotechnology and pharmaceutical processes where precise DO control is critical.

- Food & beverage production (e.g., fermentation tanks), aquaculture and hatcheries for oxygen management.

- Laboratories, R&D and industrial process control systems requiring integration with automation/SCADA.
