Dissolved Oxygen Meter Online Dissolved Oxygen Meter Manufacturing

Product Overview

- Model: DOG-2082X online dissolved oxygen (DO) meter by BOQU for continuous industrial monitoring.

- Measures DO in multiple units (%, ppm/mg/L, ppb/?g/L) and temperature with high resolution and accuracy.

- Rugged, multi-mount design (panel / wall / pipe) with IP65 rating for field use; powered from 90–260 VAC.

Product Features

- Measurement ranges: 0.0–200.0% DO; 0.00–20.00 ppm; 0.0–200.0 ppb. Temperature range ?10.0 to +130.0 °C.

- High resolution/accuracy: DO resolution 0.01/0.1; temp resolution 0.1 °C; DO accuracy to ±0.02/±0.2 (model-dependent) and temp ±0.2 °C.

- Electrode current range ?2.0 to +400 nA; polarization ?0.675 V; supports salinity (0.00–50.00 ppt) and pressure (500–9999 mBar) compensation.

- Outputs and interfaces: two isolated 4–20 mA outputs (DO and temp), RS485 Modbus RTU (9600/19200/38400), three relay outputs (max 5 A), multifunction relay, configurable cleaning cycles.

- Built-in datalogger (up to 500,000 records), backlit dot-matrix display, multilingual UI (English/Traditional/Simplified Chinese), and durable accessories for installation.

Product Value

- Reliable, continuous DO and temperature monitoring for process control, safety and regulatory compliance.

- Precise, compensated measurements (salinity/pressure/temperature) improve data quality across varying conditions.

- Integration-ready outputs (4–20 mA, Modbus, relays) enable automated control, alarm management, and easy connection to PLC/SCADA systems.

- Large onboard data storage reduces need for constant manual sampling and supports traceability/audit requirements.

Product Advantages

- Robust engineering and tested quality control from an experienced manufacturer (Shanghai Boqu Instrument Co., Ltd.) with in-house R&D and lab cooperation.

- Flexible installation (panel/wall/pipe) and IP65 protection for harsh industrial environments.

- Comprehensive signal and alarm options (isolated outputs, Modbus, multiple relays) and configurable cleaning to reduce maintenance.

- High-capacity datalogging and clear visual display for operational convenience; broad environmental and compensation ranges for versatile deployment.

- After-sales and technical support emphasis from the company to ensure stable operation and fast service.

Application Scenarios

- Wastewater treatment plants (aeration control, process monitoring, compliance reporting).

- Drinking water and environmental monitoring networks.

- Fermentation and biotechnology processes where DO control is critical.

- Food and beverage production lines for quality control.

- Aquaculture and hatcheries, industrial process tanks, laboratories, and any automated system requiring continuous DO monitoring and control.
