For water treatment plants, industrial facilities, and environmental monitoring operations requiring continuous, accurate turbidity measurement, a CE‑certified online turbidity meter with ISO 9001 quality management and RoHS compliance is the most reliable solution—and ERUN's online turbidity analyzer delivers precisely that.
The global turbidity sensor market was valued at approximately USD 850 million in 2025 and is projected to reach USD 1,460 million by 2032, growing at a CAGR of 8.0%. By 2032, the global turbidity monitor market is expected to reach USD 392 million. This rapid growth is driven by tightening water quality regulations worldwide, rapid industrialization, and the accelerating deployment of smart water infrastructure. With CE, ISO 9001, and RoHS certifications, ERUN's online turbidity meter is engineered to meet the stringent requirements of international markets and help you achieve compliance while optimizing your water treatment processes.
An online turbidity meter is a continuous monitoring instrument that measures water clarity by detecting light scattering caused by suspended particles in real time.
Turbidity is measured in NTU (Nephelometric Turbidity Units) and serves as a critical water quality parameter across drinking water treatment, wastewater treatment, industrial process control, and environmental monitoring. Unlike manual grab sampling, an online turbidity analyzer provides 24/7 real‑time data, enabling immediate detection of water quality changes, proactive maintenance, and regulatory compliance. ERUN's online turbidity meter utilizes advanced optical technology to deliver precise, continuous measurements that help optimize filtration, sedimentation, and disinfection processes.
CE, ISO 9001, and RoHS certifications are non‑negotiable for international buyers—they signal product safety, quality management, and environmental responsibility.
CE certification confirms that ERUN's online turbidity meter meets the essential health, safety, and environmental protection requirements for sale within the European Economic Area. ISO 9001 certification demonstrates that ERUN operates a robust quality management system, ensuring consistent product quality and continuous improvement. RoHS compliance guarantees that the instrument is free from hazardous substances such as lead, mercury, and cadmium, making it safe for both users and the environment. Together, these three certifications eliminate trade barriers, streamline customs clearance, and give buyers confidence in product reliability.
ERUN's online turbidity analyzer is widely used in drinking water treatment, wastewater treatment, industrial process water monitoring, and environmental monitoring.
In water treatment plants, the online turbidity meter monitors influent and effluent water quality, ensuring compliance with regulatory standards and optimizing treatment processes. In wastewater treatment, it provides real‑time data for process control and regulatory reporting. Industrial facilities rely on online turbidity monitoring for quality control in food and beverage production, pharmaceutical manufacturing, and chemical processing. Municipal water authorities use it to ensure safe drinking water delivery and to control filter backwashing operations. ERUN's online turbidity meter is also suitable for aquaculture, where real‑time turbidity monitoring helps prevent disease outbreaks.
ERUN's online turbidity meter combines high‑precision optical sensing, intelligent algorithms, and robust industrial design for reliable performance in demanding environments.
The instrument employs ISO 7027‑compliant nephelometric technology, using infrared light to eliminate color interference and ensure accurate measurements across a wide range of turbidity levels. Built‑in temperature compensation and turbidity compensation algorithms eliminate environmental interference, ensuring measurement stability. The device supports single‑point and multi‑point calibration, allowing quick recalibration using standard solutions. With a durable, IP‑rated enclosure, ERUN's online turbidity meter is designed for continuous operation in harsh industrial and municipal environments.
Selecting the right online turbidity meter depends on your measurement range, installation environment, and output requirements.
Key considerations include:
Measurement range – ensure the instrument covers your expected turbidity levels;
Installation type – choose between flow‑through, submersible, or inline configurations based on your process;
Output options – analog (4‑20mA) or digital (RS485, Modbus) for integration with SCADA or DCS systems;
Maintenance requirements – look for self‑cleaning features and low‑maintenance design.
ERUN's online turbidity meter offers flexible configuration options to meet diverse application needs, from clean drinking water monitoring to high‑turbidity wastewater and industrial process control.
Q: What is the difference between an online turbidity meter and a portable turbidity meter?
A: An online turbidity meter provides continuous, real‑time monitoring and is permanently installed in the process line. A portable turbidity meter is used for spot checking and field measurements. Online meters are essential for process control and regulatory compliance, while portable meters are ideal for troubleshooting and verification.
Q: What maintenance does an online turbidity meter require?
A: Regular cleaning of the optical window and periodic calibration using standard solutions are the primary maintenance tasks. ERUN's online turbidity meter is designed for minimal maintenance, with self‑cleaning options available.
Q: Can the online turbidity meter be integrated with my existing control system?
A: Yes. ERUN's online turbidity meter supports analog (4‑20mA) and digital (RS485, Modbus) outputs for seamless integration with SCADA, DCS, and PLC systems.
Q: What is the typical lifespan of an online turbidity meter?
A: With proper maintenance, an online turbidity meter can operate reliably for 5–10 years. ERUN's instruments are built with high‑quality components and backed by comprehensive technical support.
Q: Does ERUN provide after‑sales support for international customers?
A: Yes. ERUN offers global technical support, including installation guidance, troubleshooting, and spare parts supply.
