Extech EC400 ExStik Conductivity/TDS/Salinity Meter

The “Conductivity/TDS/Salinity Meter”(Extech EC400)  is a tool for measuring a solution’s electrical conductivity, which may be used to calculate salinity, total dissolved solids (TDS), and salt concentrations. This tool is often utilized in a number of sectors, including agricultural, food and beverage manufacturing, water treatment, and environmental monitoring.

product overview

Extech’s EC400 ExStik® has six measurement units, an internal memory that can store up to 15 labeled values for quick recall, an adjustable conductivity to TDS ratio factor from 0.4 to 1.0, and self-calibration right after powering on. The EC400 uses unique sensor technology and the most recent microprocessor chip technology to monitor conductivity, TDS, salinity, and temperature all at once. The EC400 has made testing quick, precise, and repeatable by giving you the option of adjustable cell constants at the push of a button. Includes meter, conductivity cell, guard cap, sample cup, four CR2032 batteries, and a 48″ (1.2m) neckstrap.

functions Extech EC400 ExStik Conductivity/TDS/Salinity Meter

A probe is normally used by the apparatus, and it is inserted into the solution being measured. Two electrodes in the probe allow it to gauge the solution’s electrical conductivity. Depending on the device’s calibration, the electrical conductivity is subsequently translated into a measurement of TDS or salinity.


Salts, minerals, and other organic and inorganic substances are all included in the Extech EC400 measurement of the total quantity of dissolved solids in a solution. On the other hand, salinity is a measurement of the amount of dissolved salts in a solution. These measures are critical for a number of purposes, including gauging the health of aquatic ecosystems, monitoring water quality in aquaculture systems, and determining the salt content of foods and beverages.
