For water quality monitoring requiring accurate chloride ion measurement, the ERUN-SP7-C4 Portable Chloride Ion Meter delivers laboratory-grade accuracy in a field-ready package—fully certified with CE, ISO 9001, and RoHS for global export compliance.
Chloride ion concentration is a critical water quality parameter across drinking water treatment, industrial process control, environmental monitoring, and wastewater management. Excessive chloride levels can indicate contamination, accelerate corrosion in pipelines and equipment, and compromise product quality in food and beverage production. The ERUN-SP7-C4 portable chloride ion (chloride) tester provides rapid, accurate on-site detection with a measuring range of 0.02–10.0 mg/L, error ≤±5%, and repeatability ≤2%—meeting the requirements of ASTM D512 and ISO 9297 standard methods for chloride determination in water.
Chloride ion concentration directly impacts water corrosivity, regulatory compliance, and industrial process safety.
Elevated chloride levels accelerate corrosion in metal pipes, boilers, and cooling towers, leading to equipment failure and costly downtime. In drinking water, chloride affects taste and may indicate sewage or industrial contamination. Environmental agencies worldwide enforce chloride limits for discharge into surface waters. Industrial sectors including chemical processing, pharmaceuticals, power generation, textile dyeing, and aquaculture all require routine chloride monitoring to maintain product quality and operational safety. The ERUN-SP7-C4 enables immediate on-site detection without laboratory delays, supporting real-time decision-making for water quality management.
The ERUN-SP7-C4 employs the spectrophotometric method–thiocyanate colorimetric ratio method for precise chloride determination.
This method uses a colorimetric reaction where chloride ions react with thiocyanate to produce a measurable color change, with absorbance read by the instrument’s built-in spectrophotometer. The approach offers distinct advantages over traditional titration methods: it requires smaller sample volumes, delivers results in minutes, and eliminates subjective endpoint interpretation. The instrument supports user-defined calibration curves and stores up to 100,000 data records with one-click data recovery and automatic backup. A 4.3-inch color touchscreen with bilingual interface (Chinese/English) enables intuitive operation in field conditions.
This portable chloride ion meter combines analytical precision with field-ready durability and full data management capabilities.
