Maintaining healthy water systems is essential for environmental sustainability, industrial efficiency, and public safety. One of the key indicators of water quality is dissolved oxygen (DO), a measure of the amount of oxygen gas dissolved in water. Adequate DO levels are critical for aquatic life, wastewater treatment processes, and regulatory compliance. Accurate DO measurement ensures that water quality standards are met and that ecosystems remain balanced.
For professionals and researchers, using a reliable instrument is crucial. The ERUN-SP7-A5 Portable Dissolved Oxygen Meter offers a portable, precise, and easy-to-use solution for rapid DO testing across multiple industries.
Dissolved oxygen (DO) refers to the amount of oxygen gas that is present in water. It is a fundamental parameter indicating water health because oxygen is essential for the survival of fish, microorganisms, and other aquatic organisms.
Several factors influence DO concentrations in water:
Temperature: Colder water can hold more oxygen than warmer water.
Salinity: Higher salt content reduces the solubility of oxygen.
Organic Matter & Pollution: Excess organic materials can consume oxygen during decomposition.
Photosynthesis: Aquatic plants and algae release oxygen during daylight, increasing DO.
Monitoring DO is vital for several reasons:
Environmental Health: Ensures aquatic ecosystems remain balanced.
Regulatory Compliance: Helps wastewater and industrial plants meet environmental standards.
Process Efficiency: Supports the proper functioning of biological treatment in water treatment systems.
There are several ways to measure DO, each with its own advantages and limitations:
This is a traditional laboratory method that involves adding chemical reagents to a water sample to produce a measurable reaction proportional to the DO concentration. It is highly accurate but time-consuming and requires careful handling of chemicals.
Polarographic and galvanic sensors provide real-time DO measurements by generating a current proportional to the oxygen concentration. These methods are faster than titration but require regular calibration.
Modern optical sensors use luminescence quenching technology to measure DO without consuming oxygen in the sample. They offer high precision, stability, and minimal maintenance, making them ideal for both lab and field applications.
