Accurate pH measurement is critical for water treatment, environmental monitoring, and industrial process control. Regular calibration ensures your pH sensor maintains its specified accuracy of ±0.1 pH. This guide provides step-by-step calibration instructions for the SPS-pH Water Quality Sensor based…
Choosing the right sensor for your Wastewater Treatment Plant (WWTP) depends almost entirely on what you need the data for (compliance vs. process control) and how quickly you need it. The following guide breaks down the differences between COD, TOC,…
Electrical conductivity is one of the most frequently measured parameters in water quality analysis. It indicates the ability of water to conduct an electric current, which correlates directly with the concentration of dissolved ions such as salts, minerals, and inorganic…
Safe Chlorine Levels in Drinking Water: What You Need to Know Chlorine is one of the most widely used disinfectants in public water systems worldwide. It plays a critical role in protecting communities from waterborne diseases. But how much chlorine…
What is Turbidity Turbidity is a measure of water clarity. Suspended particles—such as silt, algae, plankton, and sewage—can cause water to appear cloudy or murky. These particles scatter and absorb light, hindering its straight-line transmission through the water. A higher…
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…
