Environmental monitoring agencies, industrial wastewater treatment plants, power generation facilities, petrochemical plants, steel mills, and municipal water authorities all require reliable oil-in-water analysis for regulatory compliance and process control.
The ERUN-SP3-J4A is deployed across multiple sectors:
Environmental Protection: Surface water, groundwater, domestic sewage, and industrial wastewater monitoring
Petroleum & Petrochemical: Cooling water and wastewater oil content monitoring in refining and processing
Power Generation: Thermal power plants and steel mills monitoring circulating water and effluent
Agriculture: Irrigation and production water quality testing
Municipal Water: Water supply and drainage authorities conducting routine oil content analysis
Infrared spectrophotometry measures oil concentration by detecting the characteristic absorption of C-H bonds in petroleum hydrocarbons at specific wavenumbers (3400–2400 cm⁻¹), with the absorbance value directly proportional to oil concentration according to the Lambert-Beer law.
The ERUN-SP3-J4A follows the HJ637-2018 standard, which specifies the infrared spectrophotometric method for determining petroleum and animal/vegetable oils in industrial wastewater and domestic sewage. When sampling 500 mL with a 50 mL extract volume using a 4 cm quartz cuvette, the method detection limit reaches 0.06 mg/L with a quantitation limit of 0.24 mg/L.
The ERUN-SP3-J4A is fully certified with CE (EU safety, health, and environmental compliance), ISO 9001 (quality management system), and RoHS (restriction of hazardous substances), ensuring regulatory acceptance across global markets.
These certifications mean:
CE Marking: Complies with EU mandatory requirements for product safety and environmental protection
ISO 9001: Manufactured under strict quality management system standards with refined production control
RoHS Compliance: Free from restricted hazardous substances, meeting international environmental standards
For buyers in Europe, North America, and other regulated markets, these certifications eliminate compliance barriers and streamline import clearance.
The ERUN-SP3-J4A combines field-portable convenience (8 kg, -5 to 45°C operation) with laboratory-grade precision (0.004 mg/L detection, RSD ≤ 0.6%) at a competitive price point, backed by full international certifications.
Key differentiators include:
Simplified Operation – Built-in 7-inch color touchscreen with visualized interface and guided operating procedures eliminates the need for extensive operator training.
Intelligent Calibration – Automatic start-up calibration, standard curve calibration, and correction factor calibration ensure accuracy without manual intervention.
Comprehensive Data Management – Records sample IDs, test times, results, and extractant types; connects to Windows PCs for spectral scanning and data processing.
Built-in Printing – Integrated printer outputs stored data and full spectral scans directly in the field.
Durable Light Source – Precision grating system with operational lifespan exceeding 6,000 hours reduces maintenance costs and downtime.
Complete Accessory Kit – Includes extraction funnel, glassware, petroleum hydrocarbon standard solution, and all auxiliary accessories needed for immediate deployment.
When selecting an oil in water analyzer, prioritize instruments with wide measurement ranges (0–5000 mg/L), low detection limits (below 0.1 mg/L), international certifications (CE, ISO 9001), and field-proven durability in harsh environments.
