Congratulations on your purchase of the ExStik ® EC400 Conductivity/Total Dissolved Solids (TDS) / Salinity / Temperature meter. With the EC400’s dynamic cell-constant technology it is possible to measure a wide range of Conductivity, TDS, and Salinity with the same electrode. Careful use and maintenance will provide years of reliable service. The ExStik ® uses four (4) CR2032 Lithium Ion Batteries (included) and has an auto power off feature to preserve battery life.
The ExStik EC400 is a portable instrument designed to measure Conductivity, Total Dissolved Solids (TDS), Salinity, and Temperature. It features dynamic cell-constant technology that allows the use of a single electrode for all these measurements. The device operates on four CR2032 Lithium Ion batteries and includes an auto power-off feature.

Press and hold the MODE/HOLD button for 2 seconds to scroll through units like µS, ppm, mg/l, or ppm S.
Conductivity meter accuracy verification should be performed once per month for normal use.
Press the MODE/HOLD button to enter HOLD mode, which stores the current reading in memory.
