The Extech EC400 ExStik® has six units of measurement, inbuilt memory that records up to 15 labeled values for easy recall, an adjustable conductivity to TDS ratio factor ranging from 0.4 to 1.0, and self-calibration when powered on. The EC400 uses cutting-edge microprocessor chip technology and unique sensor technologies to simultaneously detect conductivity, TDS, salinity, and temperature. With the push of a button, the EC400 provides the flexibility of adjustable cell constants, making testing fast, accurate, and repeatable. Includes meter and conductivity cell, safety lid, sample cup, four CR2032 batteries, and a 48" (1.2m) neckstrap.
