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/µg/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.
