Turbidity Sensors Market (2024–2032) – Growing at a CAGR of 2.65% | Driven by Water Quality Monitoring, Industrial Automation, and Regulatory Compliance

The Turbidity Sensors Market is projected to expand from USD 10.14 billion in 2024 to USD 12.5 billion by 2032, growing at a CAGR of 2.65%. This growth is supported by increasing demand for real-time water quality monitoring, rising automation in water treatment plants, and stringent environmental regulations across industries and regions.
Published 24 July 2025

Turbidity sensors are critical tools used to measure the clarity or cloudiness of liquids, typically water, by detecting suspended particles that scatter light. As environmental regulations tighten and the demand for high-quality water increases across industries, turbidity sensors have become essential components in both municipal and industrial water management systems. The global market is witnessing steady growth driven by rapid urbanization, infrastructure modernization, and rising awareness of waterborne contaminants.

Market Overview and Forecast

  • Market Size (2023): USD 9.88 Billion
  • Market Size (2024): USD 10.14 Billion
  • Market Size (2032): USD 12.5 Billion
  • CAGR (2024–2032): 2.65%

Although the market shows moderate growth, it remains indispensable for sectors like water treatment, pharmaceuticals, food and beverage, and healthcare, where water purity is critical.

Key Market Drivers
