The Apera EC820 (AI532) is a high-precision, laboratory-grade benchtop meter designed for commercial nutrient-solution testing, water-quality verification, and production quality control. It measures five parameters—electrical conductivity (EC), total dissolved solids (TDS), salinity, resistivity, and temperature—using a single conductivity electrode. Its Brush-Resistant Platinum Black (BPB) glass conductivity electrode is engineered to resist fouling and maintain consistent measurement performance during frequent use. With ±0.5% full-scale accuracy, automatic 1–4-point calibration, and smart electrode-condition diagnostics, the EC820 supports repeatable testing of nutrient solutions and source water. Its Good Laboratory Practice (GLP) data-management system stores up to 500 measurement records, while USB connectivity and the included Windows PC-Link software enable data export for quality-control documentation and trend analysis.
