The Relation Between Conductivity and pH in Water: Why It Matters for Accurate Water Quality Monitoring
Understanding the relation between conductivity and pH in water is essential for anyone involved in water treatment, environmental monitoring, laboratory analysis, aquaculture, or industrial processing. These two parameters are often tested together, yet many users do not fully understand how they influence each other—or why accurate, real-time measurement is critical for reliable water quality management.
How to Check Water Hardness: A Complete Guide for Accurate Measurement
Water hardness is a critical factor that affects household appliances, industrial systems, and even aquaculture operations. Measuring water hardness accurately helps prevent scale buildup, ensures effective water treatment, and protects your plumbing and equipment. In this guide, we explore the best ways to check water hardness and highlight how the ERUN-SP9 portable multi-parameter water quality detector simplifies the
Test for Heavy Metals in Water — Your Complete Guide to Accurate Detection
Heavy metals in water, such as zinc (Zn), copper (Cu), nickel (Ni), chromium (Cr), and ammonium, pose serious risks to human health and aquatic ecosystems. Prolonged exposure, even at low concentrations, can lead to organ damage, neurological disorders, and environmental contamination. For industries, municipalities, and researchers, monitoring heavy metals is essential to ensure compliance with safety
