Digital Portable Conductivity-TDS-Salinity Meter

The Apera Instruments EC400S Portable Conductivity/TDS/Salinity/Resistivity Meter provides accurate and stable measurements with various intelligent functions and a durable structure.
Equipped with Apera's unique BPB (Brush-Resistant Platinum Black) conductivity sensor, the meter takes accurate measurements of EC, TDS, Salinity, Resistivity and temperature in a wide range (0 to 200 mS/cm)
Intelligent Functions: Quick & Easy 1 to 4 Points Auto Calibration. The Smart Self-Diagnosis helps you conduct proper calibrations and determine the condition of your probe. GLP Data management (500 groups of data storage), USB data output and power supply. Timing measuring/data logging mode and Smart calibration reminder function available. The large clear LCD displays EC and temperature simultaneously along with icons of stable readings and finished calibrations.
Reliable Structure: IP57 Waterproof and Dustproof, ideal for use in harsh environments. It comes with a complete test kit including a EC400s Portable Conductivity Meter, a Conductivity Electrode, a USB cable, PC-Link Software Disk (only works for Windows-based system), and 3 bottles of calibration solutions all in a rugged carrying case. Powered by AA Batteries.
