High-quality dissolved oxygen tester allows to switch between different units of measurement for dissolved oxygen and temperature. SISCO dissolved oxygen meter is well-suited for measuring dissolved oxygen levels and temperature in various settings, including aquariums, swimming pools, ponds, aquaculture, wastewater treatment and more.
Large LCD HD digital display with backlight
- The large LCD HD display of the dissolved oxygen meter provides high-resolution data presentation. Even in low-light environments, the backlight function ensures that the data is visible, allowing users to read information quickly and accurately.
- It is still clearly visible at night, and can be displayed with one button, regardless of the dark environment.
- The intuitive menu and display interface make operation easier, and even first-time users can easily calibrate, set up and record data, reducing operating errors.
One-button dissolved oxygen calibration
- Press and hold the "CAL/ESC" button for one-button calibration.
- Just do a 100% saturated oxygen calibration in the air, without using chemical powder.
- The dissolved oxygen probe has a quick calibration that saves time, allowing the dissolved oxygen meter to enter the working state faster before use, improving work efficiency.
- The automatic calibration function reduces the error caused by manual operation, ensures the accuracy and consistency of calibration, and thus improves the reliability of measurement results.

Detail
Q1: What is a dissolved oxygen meter?
A1: A dissolved oxygen meter is a device used to measure the amount of oxygen dissolved in a liquid, typically water. Dissolved oxygen (DO) is a crucial parameter for assessing water quality because it directly impacts the health and viability of aquatic life.Â
Q2: What does a dissolved oxygen meter measure?
A2: A dissolved oxygen meter measures the concentration of oxygen dissolved in water, typically in milligrams per liter (mg/L) or parts per million (ppm). This measurement is crucial for assessing water quality, ensuring the health of aquatic life, and optimizing processes in wastewater treatment and various industrial applications.
Q3: Is a dissolved oxygen meter accurate?
A3: Yes, a dissolved oxygen meter is generally accurate, especially when properly calibrated and maintained. Modern meters, whether using electrochemical or optical sensors, provide precise measurements of dissolved oxygen levels in water. Regular calibration against known standards and proper maintenance of the sensor are essential to ensure continued accuracy.
Tips: What factors can affect dissolved oxygen levels in water?
Several factors can affect dissolved oxygen (DO) levels in water, influencing the availability of oxygen for aquatic life and the overall water quality. Key factors include:
- Temperature: Warmer water holds less dissolved oxygen compared to colder water. As water temperature increases, the solubility of oxygen decreases, leading to lower DO levels.
Salinity: Higher salinity reduces the amount of dissolved oxygen in water. Saltwater holds less oxygen than freshwater at the same temperature and pressure. - Pressure: Atmospheric pressure influences DO levels. Higher altitudes with lower atmospheric pressure result in reduced oxygen solubility in water.
- Respiration: Respiration by aquatic organisms (fish, plants, and microorganisms) consumes oxygen, which can reduce DO levels, especially in densely populated or biologically active waters.
- Water Movement: Turbulent water, such as in rivers and streams, typically has higher DO levels due to increased aeration. Stagnant water bodies, like ponds and lakes, often have lower DO levels due to reduced mixing and aeration.
