Whether in low-oxygen or high-oxygen environments, it can provide stable and reliable dissolved oxygen data, providing strong support for the precise control of oxygenation equipment.
- pH measurement: Using the glass electrode method, the measurement range is 0-14pH, and the accuracy is ±0.1pH. By real-time monitoring of water pH, it helps users to adjust the breeding environment or production process in time to ensure the stability of water quality or products.
- Temperature monitoring: Built-in high-precision PT1000 temperature sensor, the measurement range is 0-50℃, and the accuracy is ±0.1℃. Temperature is one of the important factors affecting water quality and biological growth. By real-time monitoring of water temperature, it provides a scientific basis for optimizing the breeding environment or adjusting the production process.
2. Long-life electrode design
- PH electrode: Industrial-grade composite electrode is selected, and the reference electrode adopts a double salt bridge design, which greatly extends the service life of the electrode and reduces the frequency and cost of replacing the electrode.
- Dissolved oxygen measurement: The electrolyte-free design is adopted, and the dissolved oxygen membrane does not need to be replaced regularly, which reduces maintenance costs and improves the overall durability of the equipment.
3. Intelligent control function
- The device supports setting thresholds for dissolved oxygen, pH and temperature. When the monitoring data exceeds the set range, it can automatically trigger an alarm or control the oxygenation equipment, adjust the pH value, etc., to achieve intelligent management of the breeding environment or production process.
