Water Quality Testing Equipment Market Report 2026

The water quality testing equipment market size has grown strongly in recent years. It will grow from $4.83 billion in 2025 to $5.13 billion in 2026 at a compound annual growth rate (CAGR) of 6.1%. The growth in the historic period can be attributed to implementation of water quality regulations, industrial pollution monitoring needs, growth of laboratory testing services, public health concerns, expansion of wastewater treatment plants.

The water quality testing equipment market size is expected to see strong growth in the next few years. It will grow to $6.54 billion in 2030 at a compound annual growth rate (CAGR) of 6.3%. The growth in the forecast period can be attributed to smart water network deployment, rising environmental monitoring programs, growth of industrial compliance testing, increasing demand for field testing, investments in water safety infrastructure. Major trends in the forecast period include growth of portable testing devices, expansion of real time water monitoring, rising adoption of multi parameter testing, integration of digital data logging, demand for rapid contaminant detection.

The rising instances of water contamination are expected to support the growth of the water quality testing equipment market. Water contamination occurs when pollutants enter groundwater or bodies of water - such as lakes, rivers, and oceans - to levels that disrupt natural ecosystems or render the water unsafe for human use. Water quality testing equipment helps identify contaminants and measure various water quality parameters, enabling effective monitoring and safety assessments. For example, in September 2024, the World Health Organization (WHO), a Switzerland-based intergovernmental agency, reported that cholera cases in 2023 increased by 13% compared to 2022, while fatalities surged by 71%, claiming over 4,000 lives. These rising contamination-related health risks underscore the growing need for reliable water quality testing solutions. Therefore, increasing water contamination is driving the demand for water quality testing equipment.

Major companies in the water quality testing equipment market are focusing on product innovations such as standardized water quality test devices to maintain market competitiveness. A water quality test device measures the physical, chemical, and biological properties of water. In March 2023, NSF, a U.S.-based public health and safety organization, introduced NSF P524, the first standardized protocol designed to ensure the reliability of water quality testing devices used for drinking water. Previously, manufacturers evaluated their own devices; NSF P524 now establishes a third-party validation process. Developed in collaboration with industry and public health experts, the protocol applies to devices, sensors, and test kits that deliver real-time or rapid water quality results without requiring laboratory facilities. It rigorously evaluates device accuracy and precision across their claimed operational ranges, comparing results with established laboratory reference methods.

In April 2023, HORIBA Advanced Techno Co. Ltd., a Japan-based provider specializing in water and liquid measurement technologies, acquired Tethys Instruments SAS for an undisclosed amount. The acquisition enhances HORIBA’s water quality monitoring solutions and strengthens research and development in analytical systems. Tethys Instruments brings expertise in UV spectroscopy, which complements HORIBA’s core capabilities in electrochemistry and sampling, creating synergies that expand the company’s advanced water quality measurement offerings.
