Fast Delivery Hach Do Meter by BOQU
Product Overview
The Fast Delivery Hach DO Meter by BOQU (model DOG-2092) is a compact, panel-mount dissolved oxygen meter designed for continuous monitoring and control of dissolved oxygen in liquids. It accepts polarographic electrodes (DOG-209F or DOG-209FA), displays DO and temperature on a backlit LCD, and targets industrial and environmental applications where reliable, economical DO measurement is required.
Product Features
- Measuring range: 0.00–19.99 mg/L and 0.0–199.9% saturation; resolution 0.01 mg/L or 0.01%.
- Accuracy: ±1% F.S.; supports ppm-level DO measurement.
- Outputs and interfaces: isolated 4–20 mA output (max load 500 Ω) and RS-485 communication.
- Control and alarm: two relay outputs for high/low alarms (AC 230V 5A / AC 115V 10A).
- Usability: automatic temperature compensation, elevation and salinity settings, backlit LCD, power-down memory, and microcomputer-based storage/compensation.
Product Value
The DOG-2092 delivers high measuring performance at a competitive cost, enabling reliable, continuous DO monitoring that supports process control, regulatory compliance, and product quality assurance. Its combination of digital outputs, alarm relays, and automatic compensation reduces manual intervention and helps operators maintain optimal oxygen conditions in diverse processes.
Product Advantages
- Precision and stability for industrial DO testing and control.
- Wide functionality in a compact, easy-to-operate panel unit (automatic compensation, calibration memory, adjustable parameters).
- Robust connectivity and control: isolated 4–20 mA, RS-485, and dual relays for direct integration into control systems.
- Practical installation: standard 96×96×115 mm panel size (92×92 mm cutout).
- Backed by BOQU’s quality control, R&D support, and availability for bulk orders and fast delivery.
Application Scenarios
Suitable for continuous dissolved oxygen monitoring and control in thermal power plants, chemical fertilizer production, metallurgy, environmental protection and wastewater treatment, pharmaceutical and biochemical processes, food and beverage production, running water systems, and other industrial or environmental settings requiring ppm-level DO measurement.
