Understanding COD Sensors: The Multi-Parameter Solution for Water Quality Monitoring Chemical Oxygen Demand (COD) sensors, often referred to as multi-parameter water quality sensors, are essential tools for assessing organic pollution in water. Today, we will explore COD sensors from four…
ORP (Oxidation-Reduction Potential) electrodes are incredibly versatile tools. In simple terms, an ORP electrode measures the activity or “strength” of oxidizing and reducing agents in a solution, giving a millivolt (mV) reading that indicates the solution’s tendency to either gain…
Dissolved oxygen (DO) is one of the most vital parameters in water quality monitoring. It represents the amount of oxygen gas available to aquatic life, from the smallest bacteria to the largest fish. But how do you measure water dissolved…
An RS485 water quality sensor is a device that measures various physical and chemical parameters of water (like pH, ORP, conductivity, dissolved oxygen, turbidity, etc.) and transmits the data using the RS485 serial communication standard. The key idea is that…
Water quality monitoring has evolved significantly with advancements in optical sensing technology. Among the most innovative tools available today is the full-spectrum water quality sensor. But what exactly is it, and how does it work? In this blog, we’ll explore…
In the evolving landscape of water quality management, reliable and real-time data is crucial for making informed decisions. Among the latest innovations, the multi-wavelength water quality sensor stands out as a powerful and versatile tool. But what exactly makes it…
Dual-Wavelength Water Quality Sensor The dual-wavelength water quality sensor operates on the principle of UV-Vis absorption spectroscopy, utilising 254nm and 550nm wavelengths. It measures organic matter in water (such as COD, TOC, BOD) and includes turbidity compensation. The 254nm wavelength…
In simple terms, a nitrate sensor tells you the concentration of nitrate ions (NO₃⁻) dissolved in water. This single measurement provides critical insights into water quality, safety, and ecosystem health. Here’s a breakdown of what that reading actually tells you.…
Introduction: Why Turbidity Monitoring is Critical Turbidity, a key indicator of water quality, measures the cloudiness caused by suspended particles. Effective turbidity monitoring is non-negotiable for ensuring safe drinking water, optimizing wastewater treatment processes, and complying with environmental regulations. For…
What is Water Hardness? Water hardness refers to the total concentration of calcium ions (Ca²⁺) and magnesium ions (Mg²⁺) in water, typically measured in milligrams per litre (mg/L) as calcium carbonate (CaCO₃). This key parameter determines whether your water is…
