WATER QUALITY SENSOR MARKET SEGMENTATION

By Type

According to type, the market can be segmented into chlorine residual sensor, TOC sensor, turbidity sensor, conductivity sensor, PH sensor, and ORP sensor. 

In terms of service, TOC sensor is the largest segment. Chlorine residual sensor measures the concentration of chlorine remaining in water after disinfection processes. TOC (Total Organic Carbon) Sensor measures the total amount of organic carbon in water, indicating the overall organic pollution level. Turbidity sensor measures the cloudiness or haziness of water caused by suspended particles. Conductivity sensor measures the ability of water to conduct an electric current, which is influenced by dissolved ions. pH sensor measures the acidity or alkalinity of water. ORP (Oxidation-Reduction Potential) sensor measures the ability of a solution to act as an oxidizing or reducing agent.

By Application

Based on application, the market can be divided into commercial, industrial, chemical, environmental protection, and others.

In terms of services, industrial is the largest segment. In commercial settings, water quality sensors are used to ensure the safety and cleanliness of water for consumers. This includes monitoring water in restaurants, hotels, resorts, and recreational facilities such as swimming pools and spas. Conductivity sensors help measure the purity of water used in industrial processes, while total organic carbon (TOC) sensors ensure the absence of organic contaminants. pH and ORP sensors play a role in optimizing chemical processes and corrosion control. In chemical manufacturing, water quality is critical for both production processes and environmental impact. Water quality sensors assist in monitoring and controlling various parameters. Environmental agencies and organizations use water quality sensors to monitor natural water bodies, assess pollution levels, and protect ecosystems.

Driving Factors

Growing Awareness of Water Pollution has Increased Demand in the Market
