The ERUN-SP7 portable multi-parameter water quality analyzer delivers accurate, simultaneous detection of pH, turbidity, conductivity, COD, ammonia nitrogen, total phosphorus, and total nitrogen in a single compact unit—backed by CE, ISO 9001, and RoHS certifications. With a repeatability of 3% and optical drift under 0.002A in 20 minutes, this instrument meets the rigorous demands of wastewater treatment plants, industrial effluent monitoring, and environmental compliance testing worldwide.
A multi-parameter water quality analyzer eliminates the need for separate instruments, saving time, reducing costs, and minimizing operator error. Wastewater testing typically requires measuring physical parameters (pH, turbidity, conductivity) alongside chemical pollutants (COD, ammonia nitrogen, total phosphorus, total nitrogen). Using a single device that covers all these parameters streamlines workflow and ensures data consistency across tests.
The ERUN-SP7 supports up to 17 measurable parameters including heavy metals, residual chlorine, sulfate, nitrite, cyanide, and more—with expandable and customizable test items based on user requirements.
Regulatory compliance for wastewater discharge hinges on six core parameters: pH, turbidity, conductivity, COD, ammonia nitrogen, and total phosphorus/total nitrogen. These indicators determine whether effluent meets local environmental standards before release into natural water bodies.
pH indicates the acidity or alkalinity of wastewater, affecting both treatment efficiency and aquatic life in receiving waters. Conductivity measures the total dissolved solids, providing insight into inorganic pollutant loads.
Turbidity reflects suspended particle concentration. High turbidity can shield pathogens and reduce the effectiveness of disinfection processes.
COD quantifies the oxygen equivalent of organic matter in wastewater. The ERUN-SP7 offers three COD ranges: 5–200 mg/L (low), 200–1000 mg/L (medium), and 1000–2000 mg/L (high), with an accuracy of 5%.
Ammonia nitrogen is a key indicator of nutrient pollution. The ERUN-SP7 measures 0.02–5.00 mg/L (low range) and 5.00–25.00 mg/L (high range) with 3% accuracy.
Excess phosphorus and nitrogen cause eutrophication in lakes and rivers. The ERUN-SP7 covers TP from 0.02–10.00 mg/L and TN from 0.10–150 mg/L, both with 5% accuracy.
The ERUN-SP7 delivers laboratory-grade accuracy in a portable 4 kg package, with a power consumption under 10W. Key specifications include:
Parameter | Specification |
|---|---|
Repeatability | 3% |
Optical Stability | Drift <0.002A in 20 min |
Reading Modes | Concentration, absorbance, light transmittance |
Dimensions | 410mm × 300mm × 130mm |
Weight | 4 kg |
Power Consumption | <10W |
The instrument uses spectrophotometric methods for COD, ammonia nitrogen, total phosphorus, and total nitrogen determinations—the same principle employed by laboratory benchtop analyzers, ensuring reliable and comparable results.
CE, ISO 9001, and RoHS certifications are non-negotiable for water quality instruments entering European and North American markets. These certifications demonstrate that the equipment meets stringent safety, environmental, and quality management standards.
The ERUN-SP7 is fully compliant with:
CE Certification – Conforms to EU safety, health, and environmental protection requirements
ISO 9001 – Certified quality management system ensuring consistent product quality
RoHS Compliance – Restriction of Hazardous Substances, essential for electronics entering regulated markets
For international buyers, these certifications eliminate customs delays and regulatory hurdles, accelerating time-to-market for your wastewater monitoring projects.
Portable analyzers like the ERUN-SP7 are ideal for field sampling, spot checks, and emergency response, while online systems provide continuous real-time monitoring. Both have their place in wastewater management.
The ERUN-SP7 is designed for:
Routine effluent sampling at wastewater treatment plants
Industrial discharge compliance testing
Environmental impact assessments for new projects
Emergency spill response and contamination investigations
Its 4 kg weight and robust construction make it suitable for both laboratory and field use, giving you flexibility without compromising on accuracy.
Q: Can the ERUN-SP7 measure all the parameters I need for wastewater compliance?
A: Yes. The ERUN-SP7 detects pH, turbidity, conductivity, COD (three ranges), ammonia nitrogen (two ranges), total phosphorus (two ranges), total nitrogen (two ranges), plus heavy metals, residual chlorine, sulfate, nitrite, cyanide, and more. Test items can be expanded and customized based on your specific requirements.
Q: What certifications does the ERUN-SP7 hold?
A: The ERUN-SP7 is CE certified, ISO 9001 certified, and RoHS compliant—meeting international regulatory requirements for water quality instruments.
Q: How accurate is the ERUN-SP7?
A: Repeatability is 3%, with optical drift under 0.002A in 20 minutes. COD accuracy is 5%, ammonia nitrogen accuracy is 3%, and total phosphorus/total nitrogen accuracy is 5%.
