For drinking water compliance, industrial process control, and environmental monitoring, the ERUN-SP8-ASC-C4 portable chloride ion meter delivers lab-grade accuracy (3–1000 mg/L, ±5% or ±0.2 mg/L) in a rugged, field-ready device—fully certified with CE, RoHS, and ISO 9001 for worry-free global export.
The global chloride ion meter market was valued at USD 620.1 million in 2024 and is projected to reach USD 1,000 million by 2035, growing at a CAGR of 4.4%. Within this expanding market, portable chloride ion meters—valued at USD 744.1 million in 2024—are the fastest-growing segment, expected to reach USD 1,200 million by 2035. This growth is driven by stricter water regulations, industrial sustainability goals, and the increasing need for reliable, on-site water quality data. The ERUN-SP8-ASC-C4 is engineered to meet this demand—combining precision, durability, and full international certification.
A chloride ion water quality tester is a portable analytical instrument that measures the concentration of chloride ions (Cl⁻) in water samples using ion-selective electrode technology, providing critical data for drinking water safety, industrial corrosion control, and environmental compliance.
Chloride is one of the most common anions in natural and industrial waters. The World Health Organization (WHO) sets a guideline value of 250 mg/L for chloride in drinking water. Elevated chloride levels can indicate contamination from agricultural runoff, industrial discharge, or seawater intrusion, and can accelerate corrosion in pipelines and equipment. Regular chloride monitoring is therefore essential for municipalities, industrial plants, and environmental agencies to maintain water quality and infrastructure integrity.
The ERUN-SP8-ASC-C4 uses a chlorine ion selective electrode sensor (SUS316L) that detects chloride through the principle of light absorption and emission—specific wavelength monochromatic light is emitted into the water sample, and the intensity of emitted light is directly proportional to chloride ion concentration. This method delivers rapid, reliable results without complex laboratory procedures.
The ERUN-SP8-ASC-C4 delivers measurement accuracy of ±5% or ±0.2 mg/L (whichever is greater) across a broad detection range of 3 to 1000 mg/L, with a resolution of 0.01 mg/L—meeting the precision requirements of drinking water compliance, industrial quality control, and environmental monitoring.

This level of accuracy ensures that water quality professionals can confidently detect chloride concentrations exceeding WHO guidelines (250 mg/L) and take corrective action before compliance issues arise.
The ERUN-SP8-ASC-C4 is fully certified with CE, RoHS, and ISO 9001—three credentials that demonstrate compliance with international safety, environmental, and quality management standards, making it eligible for export to regulated markets worldwide.
CE marking confirms compliance with EU safety, health, and electromagnetic compatibility standards, including Low Voltage Directive (LVD) and Electromagnetic Compatibility (EMC) requirements. RoHS certification ensures the device is free from restricted hazardous substances such as lead, mercury, and cadmium. ISO 9001 certification verifies that the manufacturer maintains rigorous quality management systems.
For international buyers, these certifications are not optional—they are mandatory for customs clearance in the European Union and are increasingly required by procurement departments in North America, the Middle East, and Southeast Asia. The ERUN-SP8-ASC-C4 arrives with all three, eliminating regulatory barriers and providing immediate confidence in product safety and manufacturing quality.
The ERUN-SP8-ASC-C4 is designed for field and laboratory use across drinking water treatment, industrial process control, food and beverage production, aquaculture, and environmental monitoring—any application requiring rapid, accurate chloride ion concentration measurement.
Drinking Water Compliance: Municipal water utilities can test raw water, finished water, and distribution system samples to ensure chloride levels remain within WHO and EPA guidelines.
Industrial Process Control: In chemical and petrochemical facilities, chloride monitoring is critical for preventing corrosion in boilers, cooling towers, and pipelines.
Food and Beverage: Chloride concentration affects taste and product consistency; the meter helps manufacturers maintain quality standards.
Aquaculture and Agriculture: Elevated chloride levels can harm aquatic life and crops; regular testing supports sustainable operations.
Environmental Monitoring: Field teams can assess surface water, groundwater, and wastewater for chloride contamination from industrial or agricultural sources.
The ERUN-SP8-ASC-C4 combines professional-grade accuracy with exceptional durability and user-friendly features—including IP67/68 protection, 100,000+ data storage, USB data export, and intelligent sensor recognition—making it the most versatile portable chloride ion meter in its class.
Rugged Design for Field Use: The main unit is IP67-rated (dust-tight and waterproof up to 1 meter for 30 minutes), while the sensor is IP68-rated for continuous immersion. The ergonomic curved design with a rubberized non-slip hand strap ensures a firm grip even in wet conditions.
Smart Data Management: The meter stores over 100,000 data points and allows data export via USB interface. The built-in rechargeable battery charges directly via USB—no battery removal required.
Intelligent Sensor Recognition: The main unit automatically recognizes connected sensors and adapts the reading interface accordingly, ensuring accurate and intuitive data display. Sensors can also be parameterized and calibrated in the field.
Portable and Lightweight: The complete system weighs under 1.5 kg (host: 0.5 kg; sensor: <1 kg), with compact dimensions that fit easily in a field kit.
Compared to typical portable chloride meters on the market, the ERUN-SP8-ASC-C4 offers a superior combination of measurement range (3–1000 mg/L), accuracy (±5% or ±0.2 mg/L), ruggedness (IP67/IP68), and data capacity (100,000+ records)—all at a competitive price point with full CE, RoHS, and ISO 9001 certification.
Many competing portable chloride meters offer narrower measurement ranges (e.g., 0–200 mg/L or 0–500 mg/L) or lower protection ratings (IP65 or below). The ERUN-SP8-ASC-C4’s 3–1000 mg/L range covers both low-concentration drinking water applications and high-concentration industrial wastewater testing. Its IP67 main unit and IP68 sensor provide protection that competitors in the same price tier rarely match. The intelligent sensor recognition and USB data export features further differentiate it from basic models that lack digital data management capabilities.
Q: What is the difference between chlorine and chloride in water testing?
A: Chlorine (Cl₂) refers to free or total residual chlorine used for disinfection; chloride (Cl⁻) refers to the ionic form of chlorine dissolved in water. The ERUN-SP8-ASC-C4 measures chloride ion concentration, which is critical for corrosion control and contamination detection.
Q: Is the ERUN-SP8-ASC-C4 suitable for drinking water testing?
A: Yes. With a measurement range of 3–1000 mg/L and accuracy of ±5% or ±0.2 mg/L, it is ideal for testing drinking water against the WHO guideline of 250 mg/L.
Q: What is the calibration procedure?
A: The sensor can be parameterized and calibrated in the field. The main unit features an intelligent recognition function that automatically adapts to connected sensors for accurate readings.
Q: How long does the battery last?
A: The built-in rechargeable battery charges via USB. Battery life depends on usage frequency, but the device is designed for full-day field operation.
Q: Can the data be transferred to a computer?
A: Yes. Data can be exported via the USB interface, and the meter stores over 100,000 data records.
