Dissolved oxygen (DO) is one of the most important indicators of water quality. Whether in aquaculture, laboratories, environmental monitoring, or water treatment, accurate oxygen measurements help users understand changing water conditions and make better decisions.
The XDO-111 Portable Dissolved Oxygen Meter is designed for applications that require highly sensitive dissolved oxygen measurement, including low-level and ppb-level monitoring.
Why Dissolved Oxygen Matters
Oxygen levels in water can directly affect aquatic organisms, biological processes, and overall water quality. Regular monitoring helps identify changes before they become bigger problems.
For aquaculture operations, for example, maintaining suitable dissolved oxygen levels can support fish health, growth, and stable production. In environmental applications, DO measurements can help assess the condition of natural water systems.
High-Precision ppb-Level Measurement
The XDO-111 provides a measuring range of 0.01 μg/L to 20 mg/L, allowing it to detect very low dissolved oxygen concentrations.
With an accuracy of ±0.1 μg/L and a resolution of 0.01 μg/L, the meter is built for applications where small changes in dissolved oxygen need to be monitored carefully.
Fast Response for Efficient Testing
Time is important when monitoring changing water conditions. The XDO-111 features a T90 response time of less than 10 seconds, helping users obtain measurements quickly during field or laboratory testing.
Its portable design also makes it convenient for checking different sampling locations without relying on a fixed monitoring setup.
Temperature Compensation
Temperature can influence dissolved oxygen measurements. The XDO-111 includes 0–45°C temperature compensation with 0.1°C temperature accuracy, helping provide more reliable measurements across different water conditions.
Designed for Multiple Applications
The XDO-111 can be useful in a range of water-quality applications, including:
- Aquaculture – Monitor oxygen conditions in fish and shrimp farming systems.
- Water Treatment – Support water-quality and process monitoring.
- Laboratories – Perform precise dissolved oxygen measurements for testing and research.
- Environmental Monitoring – Assess dissolved oxygen conditions in natural water sources.
Portable Monitoring Wherever You Need It
The XDO-111 comes as a complete portable testing kit, making it suitable for on-site measurements. Its compact meter, probe components, tubing, and carrying case help users transport the equipment between testing locations.
