APERA EC400S Portable Conductivity / TDS / Salinity / Resistance Meter

The APERA EC400S is a rugged, portable conductivity/TDS/salinity/resistance/temperature meter engineered for demanding field and laboratory environments. Equipped with Apera's proprietary BPB (Brush Proof Platinum Black) conductivity sensor, this meter delivers accurate and stable measurements across a wide range (0-200 mS/cm). Advanced smart functions include 1-4 point automatic calibration with calibration reminder, GLP data management supporting 500 measurement records, USB data export, and real-time temperature compensation. The large backlit LCD simultaneously displays conductivity and temperature with stability and calibration verification indicators. Featuring IP57 ingress protection for water and dust resistance, the EC400S withstands harsh environments. The complete kit includes the meter, conductivity electrode, USB connectivity for data transfer, PC-Link software (Windows compatible), three pre-mixed calibration standard solutions, and rugged carrying case. Powered by AA batteries with 2-year warranty and CE certification.
