A benchtop dissolved oxygen (DO) meter is a laboratory instrument used to measure the concentration of dissolved oxygen in liquid samples. Typically placed on a lab bench, it provides accurate and stable readings, making it ideal for applications in environmental monitoring, water treatment, aquaculture, and research laboratories. Unlike portable dissolved oxygen meter, benchtop version is larger, more robust, and designed for high-precision, stationary use.
6.5 Inch Large Size Screen Display
- It is enhanced readability. A larger screen in DO meter allows for bigger fonts and clearer visual representation of numerical values.
- It reduces the chances of misreading data and helps ensure accurate monitoring and documentation.
- For users with visual impairments or for older professionals in the lab, a large screen with high contrast and large text can significantly improve accessibility.
Durable Keys in Bentchtop Dissolved Oxygen Analyzer
- Durable keys are built to withstand frequent use over extended periods without losing functionality. In many laboratory and industrial settings, benchtop DO analyzer is used daily, sometimes by multiple operators.
- Because durable keys are less prone to malfunction, they require less frequent servicing or replacement. This reduces downtime and maintenance costs.
Applications
SISCO dissolved oxygen meters are specially used to measure the dissolved oxygen content in water. Dissolved oxygen refers to the oxygen dissolved in water, which is very important for aquatic organisms. It is mainly used in aquaculture, wastewater treatment, domestic water, environmental water quality testing, and other fields.

Structure:
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.
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: How to maintain a benchtop dissolved oxygen meter?
To maintain a benchtop dissolved oxygen (DO) meter, regularly calibrate it using a certified standard or air-saturated water. Clean the DO probe gently with distilled water and a soft cloth to avoid damaging the membrane. Store the probe in a moist environment to prevent drying. Avoid exposure to extreme temperatures and keep the device in a clean, dry area. Check cables and connectors for damage regularly.
